DESCRIPTION: This joint computational project between CARB and TIGR has three aims: 1) Initial investigation of the function of genes by means of sequence and database searches of evolutionary relationships. Established sequence search methods, as well as more advanced techniques, including Hidden Markov Models and threading, will be used. 2) Analysis of the experimentally derived structures to deduce function. The folds of new structures will be compared with known folds and their functions. The catalytic sties of enzymes as well as metal binding sites will be identified by comparison with a database of known three-dimensional motifs. Ligand binding sties will be identified with the aid of two different methods of surface topology analysis, electrostatic potentials, and by an examination of evolutionary conservation of the surface. Possible ligands will be identified by the use of docking techniques developed for drug design, together with a library of natural ligands. Sites of interaction with other macromolecules will be identified by analysis of surface composition and evolutionary conservation. 3) Distribution and collection of information about the function of each protein studied. Information about function derived from the program will be made available rapidly via a Web site, and research groups likely to be interested in particular functions will be contacted.

描述：CARB和TIGR之间的联合计算项目 三个目标：1）通过基因功能的初步研究， 进化关系的序列和数据库搜索。建立 序列搜索方法，以及更先进的技术，包括 隐马尔可夫模型和线程，将被使用。2)分析 实验衍生的结构来推断功能。新的褶皱 结构将与已知的褶皱及其功能进行比较。的 酶的催化位点以及金属结合位点将被 通过与已知的三维数据库进行比较来识别 图案配体结合位点将借助于两个 不同的表面拓扑分析方法，静电势， 并通过对表面进化保守性的研究。 可能的配体将通过使用对接技术来鉴定 开发用于药物设计，以及天然配体库。 与其他大分子相互作用的位点将通过 表面组成分析和进化保护。第三章 分发和收集有关每个机构功能的信息 蛋白质研究有关从程序派生的函数的信息将 可以通过网站迅速提供，研究小组可能会 有兴趣参加特别活动的人士，可与我们联络。
