Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedX-ray structures of trypsin from bovine pancreas inactivated by diphenyl [N-(benzyloxycarbonyl)amino](4-amidinophenyl)methanephosphonate [Z-(4-AmPhGly)P(OPh)2] were determined at 113 and 293 K to 1.8 angstrom resolution and refined to R factors of 0.211 (113 K) and 0. 178 (293 K). The structures reveal a tetrahedral phosphorus covalently bonded to the O gamma of the active site serine. Covalent bond formation is accompanied by the loss of both phenoxy groups. The D-stereoisomer of Z-(4-AmPhGly)P-(OPh)2 is not observed in the complex. The L-stereoisomer of the inhibitor forms contacts with several residues in the trypsin active site. One of the phosphonate oxygens is inserted into the oxyanion hole and forms hydrogen bonds to the amides of Gly193, Asp194, and Ser195. The second phosphonate oxygen forms hydrogen bonds to N epsilon 2 of His 57. The p-amidinophenylglycine moiety binds into the trypsin primary specificity pocket, interacting with Asp189. The amide forms a hydrogen bond to the carbonyl oxygen atom of Ser214. The inhibitor moiety, from the 113 K structure of trypsin inactivated by the reaction product of Z-(4-AmPhGly)P(OPh)2, was docked into human thrombin [Bode, W., Mayr, I., Baumann, U., Huber, R., Stone, S. R., & Hofsteenge, J. (1989) EMBO J. 8, 3467-3475] and energy minimized. The inhibitor fits well into the thrombin active site, forming favorable contacts similar to those in the trypsin complex with no bad contacts.
