The role of subsite +2 of the Trichoderma reesei beta-mannanase TrMan5A in hydrolysis and transglycosylation
The N-terminal catalytic module of beta-mannanase TrMan5A from the filamentous fungus Trichoderma reesei is classified into family 5 of glycoside hydrolases. It is further classified in clan A with a (beta/alpha)(8) barrel configuration and has two catalytic glutamates (E169 and E276). It has at least five other residues conserved in family 5. Sequence alignment revealed that an arginine (R171 in
