Glycoside Hydrolase Family 6

Activities in Familyendoglucanase (EC 3.2.1.4); cellobiohydrolase (EC 3.2.1.91)
Mechanism Inverting
Catalytic Nucleophile/BaseAsp (experimental)
Catalytic Proton DonorAsp (experimental)
Noteformerly known as cellulase family B. The cellobiohydrolases of this family are widely believed to act processively from the non-reducing ends of cellulose chains to generate cellobiose.
