SUBTILISIN DY IN COMPLEX WITH THE SYNTHETIC INHIBITOR N-BENZYLOXYCARBONYL-ALA-PRO-PHE-CHLOROMETHYL KETONESUBTILISIN DY IN COMPLEX WITH THE SYNTHETIC INHIBITOR N-BENZYLOXYCARBONYL-ALA-PRO-PHE-CHLOROMETHYL KETONE
Structural highlights
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 crystal structure of subtilisin DY inhibited by N-benzyloxycarbonyl-Ala-Pro-Phe-chloromethyl ketone has been solved by molecular replacement with subtilisin Carlsberg as the starting model. The model has been refined to a crystallographic R factor (= sigma absolute value [(absolute value Fo) - (absolute value Fc)] / sigma (absolute value of Fo) of 15.1% using X-ray diffraction data to 0.175 nm resolution. Subtilisin DY is an alkaline proteinase from the X-irradiated Japanese strain DY of Bacillus licheniformis, which normally produces subtilisin Carlsberg. It has very similar properties to subtilisin Carlsberg, with a slightly enhanced resistance to heat and guanidine hydrochloride-induced denaturation, in spite of the fact that the sequences of the two enzymes differ in 31 positions out of 274 residues. The close similarity in overall three-dimensional structure of subtilisins DY and Carlsberg and also their physicochemical properties, such as activity and stability, shows that nature aided by X-irradiation for rapid 'evolution' is able to accommodate considerable changes in sequence without substantial changes in property. Crystal structure of subtilisin DY, a random mutant of subtilisin Carlsberg.,Eschenburg S, Genov N, Peters K, Fittkau S, Stoeva S, Wilson KS, Betzel C Eur J Biochem. 1998 Oct 15;257(2):309-18.
