FAMILY 10 XYLANASE

Overview

Thermostability is an important property of industrially significant, hydrolytic enzymes: understanding the structural basis for this attribute, will underpin the future biotechnological exploitation of these, biocatalysts. The Cellvibrio family 10 (GH10) xylanases display, considerable sequence identity but exhibit significant differences in, thermostability; thus, these enzymes represent excellent models to examine, the structural basis for the variation in stability displayed by these, glycoside hydrolases. Here, we have subjected the intracellular Cellvibrio, mixtus xylanase CmXyn10B to forced protein evolution. Error-prone PCR and, selection identified a double mutant, A334V/G348D, which confers an, increase in thermostability. The mutant has a Tm 8 degrees C higher than, the ... [(full description)]
