Function[SUBS_BACLE] Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe three-dimensional structures of engineered variants of Bacillus lentus subtilisin having increased enzymatic activity, K27R/N87S/V104Y/N123S/T274A (RSYSA) and N76D/N87S/S103A/V104I (DSAI), were determined by X-ray crystallography. In addition to identifying changes in atomic position we report a method that identifies protein segments having altered flexibility. The method utilizes a statistical analysis of variance to delineate main-chain temperature factors that represent significant departures from the overall variance between equivalent regions seen throughout the structure. This method reveals changes in main-chain mobility in both variants. Residues 125-127 have increased mobility in the RSYSA variant while residues 100-104 have decreased mobility in the DSAI variant. These segments are located at the substrate-binding site and changes in their mobility are believed to relate to the observed changes in proteolytic activity. The effect of altered crystal lattice contacts on segment flexibility becomes apparent when identical variants, determined in two crystal forms, are compared with the native enzyme. Engineered Bacillus lentus subtilisins having altered flexibility.,Graycar T, Knapp M, Ganshaw G, Dauberman J, Bott R J Mol Biol. 1999 Sep 10;292(1):97-109.
