Active-site mutations improved the transglycosylation activity of Stenotrophomonas maltophilia chitinase A.

Abstract

Transglycosylation (TG) by family 18 chitinases is of special interest due to the many biological applications of long-chain chitooligosaccharides (CHOS). In the current study, the TG activity of chitinase A from Stenotrophomonas maltophilia (StmChiA) was improved through structure-guided mutations within and around the active site. Three independent… (More)
