Background
The fingerprint of a molecule is a bitstring based on its structure, constructed such that structurally similar molecules will have similar fingerprints. Molecular fingerprints can be used in an initial phase of drug development for identifying novel drug candidates by screening large databases for molecules with fingerprints similar to a query fingerprint. 相似文献Background
The neighbor-joining method by Saitou and Nei is a widely used method for constructing phylogenetic trees. The formulation of the method gives rise to a canonical Θ(n 3) algorithm upon which all existing implementations are based. 相似文献Hyalomma asiaticum and H. anatolicum are tick species in Eurasia and Africa with major medical and veterinary significance. Beside their direct pathogenic effects, H. asiaticum and H. anatolicum are vectors of important diseases of livestock and in some instances of zoonoses. In search of ways to address the increasing incidence of global acaricide resistance, tick control through vaccination is regarded as a sustainable alternative approach. Cathepsin L-like cysteine protease (CPL) is a potent hemoglobinase, and plays important roles in the digestion of blood acquired from a host. CPL from H. anatolicum (HanCPL) with high similarity (>?90%) for H. asiaticum CPL (HasCPL) were aligned by in silico analysis. After further in vitro validation, the anti-HasCPL sera have cross-reactivity between the different total native protein of life stages and tissues for H. asiaticum and H. anatolicum. Furthermore, we further confirmed that recombinant HasCPL (rHasCPL) immunized rabbits were partially cross-protected (54.8%) by H. anatolicum infestation.
