STRUCTURE OF CBM25 FROM BACILLUS HALODURANS AMYLASE IN COMPLEX WITH MALTOTETRAOSE
Overview
Starch-hydrolyzing enzymes lacking alpha-glucan-specific, carbohydrate-binding modules (CBMs) typically have lowered activity on, granular starch relative to their counterparts with CBMs. Thus, consideration of starch recognition by CBMs is a key factor in, understanding granular starch hydrolysis. To this end, we have dissected, the modular structure of the maltohexaose-forming amylase from Bacillus, halodurans (C-125). This five-module protein comprises an N-terminal, family 13 catalytic module followed in order by two modules of unknown, function, a family 26 CBM (BhCBM26), and a family 25 CBM (BhCBM25). Here, we present a comprehensive structure-function analysis of starch and, alpha-glucooligosaccharide recognition by BhCBM25 and BhCBM26 using UV, methods, isothermal titration ...
