The frequent emergence of drug-resistant bacteria has created an urgent demand for new antimicrobial agents. Traditional methods of novel antibiotic development are almost obsolete. Antimicrobial peptides (AMPs) are now regarded as a potential solution to revive the traditional methods of antibiotic development, although, until now, many AMPs have failed in clinical trials. A comprehensive database of AMPs with information about their antimicrobial activity and cytotoxicity will help promote the process of finding novel AMPs with improved antimicrobial activity and reduced cytotoxicity and eventually accelerate the speed of translating the discovery of new AMPs into clinical or preclinical trials. LAMP, a database linking AMPs, serves as a tool to aid the discovery and design of AMPs as new antimicrobial agents. The current version of LAMP has 5,547 entries, comprising 3,904 natural AMPs and 1,643 synthetic peptides. The database can be queried using either simply keywords or combinatorial conditions searches. Equipped with the detailed antimicrobial activity and cytotoxicity data, the cross-linking and top similar AMPs functions implemented in LAMP will help enhance our current understanding of AMPs and this may speed up the development of new AMPs for medical applications.

GMEs are genetically modified enzybiotics created through molecular engineering approaches to deal with the increasing problem of antibiotic resistance prevalence. We present a fully manually curated database, GMEnzy, which focuses on GMEs and their design strategies, production and purification methods, and biological activity data. GMEnzy collects and integrates all available GMEs and their related information into one web based database. Currently GMEnzy holds 186 GMEs from published literature. The GMEnzy interface is easy to use, and allows users to rapidly retrieve data according to desired search criteria. GMEnzy’s construction will increase the efficiency and convenience of improving these bioactive proteins for specific requirements, and will expand the arsenal available for researches to control drug-resistant pathogens. This database will prove valuable for researchers interested in genetically modified enzybiotics studies. GMEnzy is freely available on the Web at http://biotechlab.fudan.edu.cn/database/gmenzy/. 相似文献

The National Institutes of Health/Department of Energy Human Genome Project has been funding directed research for only 5 years, and it is understandably difficult to cite important research advances directly attributable to the project. However, the project has been constructive in fostering multidisciplinary group research and an inspiring and synergistic "just do it" attitude in both political and scientific circles, domestically and abroad. This collaborative spirit has spawned large-scale genetic and physical mapping projects, with the most impressive and useful results to date being the dense genetic maps produced by the Généthon, a French organization largely supported by the French muscular dystrophy association. With the genetic and physical map reagents now becoming available, disease-gene cloning is proceeding at an increasingly rapid pace. More important than the predictable acceleration of disease-gene mapping are the unpredictable benefits: Will a dense PCR-based dinucleotide-repeat genetic map open novel alternative approaches to disease-gene isolation? Will it become possible to localize disease genes by simply analyzing unrelated, isolated probands rather than the rarer "extended family"? Proband-based "linkage-disequilibrium cloning" may become possible if adequate density, informativeness, and stability of polymorphic loci are obtained. In addition, "genome exclusion cloning" will be added to the established positional, candidate-gene, and functional-disease-gene-cloning experimental approaches. The anticipated exponential expansion of human genetic disease information over the remainder of the 10-year tenure of the Human Genome Project unveils critical yet unresolved issues for medical education and the practice of medicine.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

在克隆人类遗传病致病基因的过程中,寻找染色体特定区段的转录序列成为主要的限速步骤.早期的努力集中在筛选cDNA文库,找寻进化上保守的DNA序列,以及Northern杂交.最近几年,在人类基因组计划的推动下,发展了数种有效的寻找基因的新方法.这些方法不但扩展了寻找新基因的染色体区段,而且能在不依赖基因表达的情况下进行筛选.文中综述新旧几种寻找基因的方法,并讨论它们各自的优点与局限. 相似文献

The apple (Malus domestica) is one of the most economically important fruit crops in the world, due its importance to human nutrition and health. To analyze the function and evolution of different apple genes, we developed apple gene function and gene family database (AppleGFDB) for collecting, storing, arranging, and integrating functional genomics information of the apple. The AppleGFDB provides several layers of information about the apple genes, including nucleotide and protein sequences, chromosomal locations, gene structures, and any publications related to these annotations. To further analyze the functional genomics data of apple genes, the AppleGFDB was designed to enable users to easily retrieve information through a suite of interfaces, including gene ontology, protein domain and InterPro. In addition, the database provides tools for analyzing the expression profiles and microRNAs of the apple. Moreover, all of the analyzed and collected data can be downloaded from the database. The database can also be accessed using a convenient web server that supports a full-text search, a BLAST sequence search, and database browsing. Furthermore, to facilitate cooperation among apple researchers, AppleGFDB is presented in a user-interactive platform, which provides users with the opportunity to modify apple gene annotations and submit publication information for related genes. AppleGFDB is available at http://www.applegene.org or http://gfdb.sdau.edu.cn/. 相似文献

The Human Genome Project is a US-based molecular biological project, the results of which are likely to be implemented on humans. The sociopolitical dimension of this is highly neglected. The aim of the conference was to fill this gap by drawing together scientists of natural and political sciences to discuss the consequences of the Human Genome Project across the disciplines. 相似文献

Mitochondrion plays a central role in diverse biological processes in most eukaryotes, and its dysfunctions are critically involved in a large number of diseases and the aging process. A systematic identification of mitochondrial proteomes and characterization of functional linkages among mitochondrial proteins are fundamental in understanding the mechanisms underlying biological functions and human diseases associated with mitochondria. Here we present a database MitProNet which provides a comprehensive knowledgebase for mitochondrial proteome, interactome and human diseases. First an inventory of mammalian mitochondrial proteins was compiled by widely collecting proteomic datasets, and the proteins were classified by machine learning to achieve a high-confidence list of mitochondrial proteins. The current version of MitProNet covers 1124 high-confidence proteins, and the remainders were further classified as middle- or low-confidence. An organelle-specific network of functional linkages among mitochondrial proteins was then generated by integrating genomic features encoded by a wide range of datasets including genomic context, gene expression profiles, protein-protein interactions, functional similarity and metabolic pathways. The functional-linkage network should be a valuable resource for the study of biological functions of mitochondrial proteins and human mitochondrial diseases. Furthermore, we utilized the network to predict candidate genes for mitochondrial diseases using prioritization algorithms. All proteins, functional linkages and disease candidate genes in MitProNet were annotated according to the information collected from their original sources including GO, GEO, OMIM, KEGG, MIPS, HPRD and so on. MitProNet features a user-friendly graphic visualization interface to present functional analysis of linkage networks. As an up-to-date database and analysis platform, MitProNet should be particularly helpful in comprehensive studies of complicated biological mechanisms underlying mitochondrial functions and human mitochondrial diseases.
