Fig. 9From: Purification and characterization of thermoactive serratiopeptidase from Serratia marcescens AD-W2Stereoview of the zinc-binding site in the Serratiopeptidase. The zinc ion is shown as a purple ball. The active site of serratiopeptidase from S. marcescens AD-W2 shows the zinc ion coordinated as Zn.1, His.192, His.196, His.202, Glu.193, and Tyr.232 is forming a distorted trigonal bipyramidal catalytic active centerBack to article page
