ESTHER (for esterases, alpha/betahydrolase enzyme and relatives) is a database of sequences phylogenetically related to cholinesterases. These sequences define a homogeneous group of enzymes (carboxylesterases, lipases and hormone-sensitive lipases) sharing a similar structure of a central beta-sheet surrounded by alpha-helices. Among these proteins a wide range of functions can be found (hydrolases, adhesion molecules, hormone precursors). The purpose of ESTHER is to help comparison of structures and functions of members of the family. Since the last release, new features have been added to the server. A BLAST comparison tool allows sequence homology searches within the database sequences. New sections are available: kinetics and inhibitors of cholinesterases, fasciculin-acetylcholinesterase interaction and a gene structure review. The mutation analysis compilation has been improved with three-dimensional images. A mailing list has been created.
ESTHER(酯酶、α/β水解酶及相关酶类)是一个与胆碱酯酶有系统发育关系的序列数据库。这些序列定义了一组同源酶(羧酸酯酶、脂肪酶和激素敏感性脂肪酶),它们共享一个由α螺旋包围的中央β折叠的相似结构。在这些蛋白质中可以发现广泛的功能(水解酶、粘附分子、激素前体)。ESTHER的目的是帮助比较该家族成员的结构和功能。自上次发布以来,服务器添加了新功能。一个BLAST比较工具允许在数据库序列中进行序列同源性搜索。新增了一些板块:胆碱酯酶的动力学和抑制剂、束丝菌素-乙酰胆碱酯酶相互作用以及基因结构综述。突变分析汇编通过三维图像得到了改进。还创建了一个邮件列表。
