Update of KEYnet: a gene and protein names database for biosequences functional organisation

KEYnet is a database where gene and protein names are hierarchically structured. Particular care has been devoted to the search and organisation of synonyms. The structuring is based on biological criteria in order to assist the user in data search and to minimise the risk of information loss. Links to the EMBL data library by the entry name and the accession number are implemented. KEYnet is available through the WWW at the following site: http://www.ba.cnr.it/keynet.html     

Database on the structure of small ribosomal subunit RNA.

The Antwerp database on small ribosomal subunit RNA offers over 4300 nucleotide sequences (August 1995). All these sequences are stored in the form of an alignment based on the adopted secondary structure model, which in turn is corroborated by the observation of compensating substitutions in the alignment. Besides the primary and secondary structure information, literature references, accession numbers and detailed taxonomic information are also compiled. The complete database is made available to the scientific community through anonymous ftp and World Wide Web(WWW).     

Design and realization of an on-line database for multidimensional microscopic images of biological specimens

The BioImage database is a new scientific database for multidimensional microscopic images of biological specimens, which is available through the World Wide Web (WWW). The development of this database has followed an iterative approach, in which requirements and functionality have been revised and extended. The complexity and innovative use of the data meant that technical and biological expertise has been crucial in the initial design of the data model. A controlled vocabulary was introduced to ensure data consistency. Pointers are used to reference information stored in other databases. The data model was built using InfoModeler as a database design tool. The database management system is the Informix Dynamic Server with Universal Data Option. This object-relational system allows the handling of complex data using features such as collection types, inheritance, and user-defined data types. Informix datablades are used to provide additional functionality: the Web Integration Option enables WWW access to the database; the Video Foundation Blade provides functionality for video handling.     

Novel developments with the PRINTS protein fingerprint database.

The PRINTS database of protein family 'fingerprints' is a diagnostic resource that complements the PROSITE dictionary of sites and patterns. Unlike regular expressions, fingerprints exploit groups of conserved motifs within sequence alignments to build characteristic signatures of family membership. Thus fingerprints inherently offer improved diagnostic reliability by virtue of the mutual context provided by motif neighbours. To date, 600 fingerprints have been constructed and stored in PRINTS, representing a 50% increase in the size of the database in the last year. The current version, 13.0, encodes approximately 3000 motifs, covering a range of globular and membrane proteins, modular polypeptides, and so on. The database is accessible via UCL's Bioinformatics World Wide Web (WWW) server at http://www.biochem.ucl.ac.uk/bsm/dbbrowser / . We describe here progress with the database, its Web interface, and a recent exciting development: the integration of a novel colour alignment editor (http://www.biochem.ucl.ac.uk/bsm/dbbrowser++ +/CINEMA ), which allows visualisation and interactive manipulation of PRINTS alignments over the Internet.     

The guide RNA database (3.0).

The RNA editing process within the mitochondria of kinetoplastid organisms is controlled by small, trans -acting RNA molecules referred to as guide RNAs. The guide RNA database is a compilation of published guide RNA sequences, currently containing 254 entries from 11 different organisms. Additional information includes RNA secondary and tertiary structure models, information on the gene localisation, literature citations and other relevant facts. The database can be accessed through the World Wide Web (WWW) at http://www.biochem.mpg.de/ goeringe/     

BCDB - A database for breast cancer research and information

In pursuit of a better updated source including 'omics' information for breast cancer, Breast Cancer Database (BCDB) has been developed to provide the researcher with the quick overview of the Breast cancer disease and other relevant information. This database comprises of myriad of information about genes involved in breast cancer, its functions and drug molecules which are currently being used in the treatment of breast cancer. The data available in BCDB is retrieved from the biomedical research literature. It facilitates the user to search information on gene, its location in chromosome, functions and its importance in cancer diseases. Broadly, this can be queried by giving gene name, protein name and drug name. This database is platform independent, user friendly and freely accessible through internet. The data present in BCDB is directly linked to other on-line resources such as NCBI, PDB and PubMed. Hence, it can act as a complete web resource comprising gene sequences, drug structures and literature information related to breast cancer, which is not available in any other breast cancer database. AVAILABILITY: The database is freely available at http://122.165.25.137/bioinfo/breastcancerdb/     

YPL.db: the Yeast Protein Localization database

The Yeast Protein Localization database (YPL.db) contains information about the localization patterns of yeast proteins resulting from microscopic analyses. The data and parameters of the experiments to obtain the localization information, together with images from confocal or video microscopy, are stored in a relational database, building an archive of, and the documentation for, all experiments. The database can be queried based on gene name, protein localization, growth conditions and a number of additional parameters. All experiment parameters are selectable from predefined lists to ensure database integrity and conformity across different investigators. The database provides a structure reference resource to allow for better characterization of unknown or ambiguous localization patterns. Links to MIPS, YPD and SGD databases are provided to allow fast access to further information not contained in the localization database itself. YPL.db is available at http://ypl.tugraz.at.     

Seq2Struct: a resource for establishing sequence-structure links

SUMMARY: Several methods for establishing cross-links between Protein Data Bank (PDB) structures or Structural Classification of Proteins (SCOP) domains and Swiss-Prot + TrEMBL sequences (or vice versa) rely on database annotations. Alternatively, sequence alignment procedures can be used. In this study, we describe Seq2Struct, a web resource for the identification of sequence-structure links. The resource consists of an exhaustive collection of annotated links between Swiss-Prot + TrEMBL and PDB + SCOP database entries. Links are based on pre-established highly reliable thresholds and stored in a relational database, which has been enhanced using annotations derived from Swiss-Prot, PDB, SCOP, GOA and DSSP databases. The Seq2Struct database contents, supported by a WWW web interface, can be queried both online and downloaded. AVAILABILITY: The Seq2Struct resource, with related documentation, is available at http://surface.bio.uniroma2.it/seq2struct/ CONTACT: seq2struct@cbm.bio.uniroma2.it.     

A template for the future: digitizing and databasing a taxonomic illustration collection

This is the first iconographic taxonomic database intended as an everyday tool for the practising taxonomist, that allows access to the original drawings used to describe species. We demonstrate the system with water mites (Acari, Parasitengona, Hydrachnidia) but it may be used with any other plant or animal group. Query by genus or species leads to the original drawings and any additional images associated to that particular name. At present, the database includes images from more than 4,000 species (around 38,000 illustrations) and is easily expandable. Copyright does not allow the database to be used in an open WWW context, but it can be an extremely useful tool in private taxonomic applications.     

The European small subunit ribosomal RNA database

The European database of the Small Subunit (SSU) Ribosomal RNA is a curated database that strives to collect all information about the primary and secondary structure of completely or nearly-completely sequenced rRNAs. Furthermore, the database compiles additional information such as literature references and taxonomic status of the organism the sequence was derived from. The database can be consulted via the WWW at URL http://rrna.uia.ac.be/ssu/. Through the WWW, sequences can be easily selected either one by one, by taxonomic group, or by a combination of both, and can be retrieved in different sequence and alignment formats.     

Database on the structure of large ribosomal subunit RNA.

The latest release of the large ribosomal subunit RNA database contains 429 sequences. All these sequences are aligned, and incorporate secondary structure information. The rRNA WWW Server at URL http://rrna.uia.ac.be/ provides researchers with an easily accessible resource to obtain the data in this database in a number of computer-readable formats. A new query interface has been added to the server. If necessary, the data can also be obtained by anonymous ftp from the same site.     

Databases and software for the analysis of mutations in the human p53 gene, the human hprt gene and the lacZ gene in transgenic rodents.

We have created databases and software applications for the analysis of DNA mutations in the human p53 gene, the human hprt gene and the rodent transgenic lacZ locus. The databases themselves are stand-alone dBase files and the software for analysis of the databases runs on IBM- compatible computers. The software created for these databases permits filtering, ordering, report generation and display of information in the database. In addition, a significant number of routines have been developed for the analysis of single base substitutions. One method of obtaining the databases and software is via the World Wide Web (WWW). Open home page http://sunsite.unc.edu/dnam/mainpage.ht ml with a WWW browser. Alternatively, the databases and programs are available via public ftp from anonymous@sunsite.unc.edu. There is no password required to enter the system. The databases and software are found in subdirectory pub/academic/biology/dna-mutations. Two other programs are available at the WWW site, a program for comparison of mutational spectra and a program for entry of mutational data into a relational database.     

GIF-DB, a WWW database on gene interactions involved in Drosophila melanogaster development.

GIF-DB (Gene Interactions in the Fly Database) is a new WWW database (http://www-biol.univ-mrs.fr/ approximately lgpd/GIFTS_home_page. html ) describing gene molecular interactions involved in the process of embryonic pattern formation in the flyDrosophila melanogaster. The detailed information is distributed in specific lines arranged into an EMBL- (or SWISS-PROT-) like format. GIF-DB achieves a high level of integration with other databases such as FlyBase, EMBL and SWISS-PROT through numerous hyperlinks. The original concept of interaction databases examplified by GIF-DB could be extended to other biological subjects and organisms so as to study gene regulatory networks in an evolutionary perspective.     

Identification of gene-related Korean patents and construction of a database server for Korean patent sequences

With the advent of high-throughput techniques, the number of patent applications containing biological sequences has been increasing rapidly in Korea. However, there is little information on gene relatedness of the Korean patent sequences. The primary aims of this study are two-fold. First, we associated Korean patent applications with genes. Second, we have constructed a database server, named Patome@Korea, to provide the gene-patent map and the Korean patent data containing biological sequences. To associate the sequences with genes, we have received patent sequence data from the Korean Intellectual Property Office (KIPO) and annotated them with RefSeq and Entrez Gene. Through the association analysis, we found that nearly 14.7% of human genes were related to Korean patenting, compared to 25% of human genes in the US patent. We have consolidated the association results and the patent sequence data to a relational database and implemented a web-based user interface to provide search service. The database can be queried using application number, applicant, titles, gene ID/name, and RefSeq number. We also provide web-based BLAST facility to allow users to compare their sequences against patent sequences. Equal contribution.     

Adapting EcoCyc for use on the World Wide Web

The World Wide Web (WWW) offers the potential to deliver specialized information to an audience of unprecedented size. Along with this exciting new opportunity comes a challenge for software developers: instead of rewriting our software applications to operate over the WWW, how can we maximize software reuse by retrofitting existing applications? We have developed a Web server tool. written in Common Lisp, that allows existing graphical user interface applications written using the Common Lisp Interface Manager (CLIM) to hook easily into the WWW. This tool — CWEST (CLIM-WEb Server Tool, pronounced “quest”) — was developed to operate with EcoCyc, an electronic encylopedia of the genes and metabolism of the bacterium E. coli. EcoCyc consists of a database of objects relevant to E. coli biochemistry and a user interface, implemented in CLIM, that runs on the X-window system and generates graphical displays appropriate to biological objects. Each query to the EcoCyc WWW server is treated as a command to the EcoCyc program, which dynamically generates an appropriate CLIM drawing. CWEST translates that drawing, which can be a mixture of text and graphics, into the HyperText Markup Language (HTML) and/or the Graphics Interchange Format (GIF), which are returned to the client. Sensitive regions embedded in the CLIM drawing are converted to hyperlinks with Universal Resource Locators (URLs) that generate further EcoCyc queries. This tight coupling of CLIM output with Web output makes CLIM a powerful high-level programming tool for Web applications. The flexibility of Common Lisp and CLIM made implementation of the server tool surprisingly easy, requiring few changes to the existing EcoCyc program. The results can be seen at URL http://www.ai.sri.com/ecocyc/browser.html. We have made CWEST available to the CLIM community at large, with the hope that it will spur other software developers to make their CLIM applications available over the WWW.
