基于实验合成的五配位磷氨基酸晶体的平方锥和三角锥的结构,以及氨基酸侧链参与形成五配位磷化学结构实验的基础上,设计了软件来搜索国际蛋白数据库中可能形成五配位磷结构的含磷蛋白.利用自主编写的软件研究发现,国际蛋白质数据库(PDB库)收录的398个含磷的蛋白激酶中,有382个蛋白激酶(96%)在活化过程中可能经历了五配位磷化学过渡态或中间体.例如1H8E蛋白的Lys16的NZ原子与GNP2的P原子形成了可能的五配位化学结构,将该结构与实验得到的氨基酸小分子晶体的实际五配位磷结构进行叠加,结构符合很好,相关结构的偏差RMSD值为0.71?文中的软件下载地址为ftp//166.111.28.228,软件版权登记号2002SR2943.
Based on the experimentally synthesized square pyramidal and triangular pyramidal structures of five-coordinated phosphoamino acid crystals and the experimental investigation of the five-coordinated phosphorus chemical structure involved in the side chain formation of amino acids, a software was designed to search for possible five-coordinate Phosphoprotein of Phosphorus Structure Using self-prepared software, 382 protein kinases (96%) out of the 398 phosphorus-containing protein kinases included in the International Protein Database (PDB) database may have undergone five For example, the NZ atom of Lys16 of 1H8E protein forms a possible pentacoordinated chemical structure with the P atom of GNP2, and this structure can be compared with the actual pentacoordinated phosphorus of the experimental amino acid small molecule crystal The structure is superposed, the structure is in good accordance with the RMSD value of the related structure deviation is 0.71.
