Glycoside Hydrolase Family 3

Activities in Familyβ-glucosidase (EC 3.2.1.21); xylan 1,4-β-xylosidase (EC 3.2.1.37); β-glucosylceramidase (EC 3.2.1.45); β-N-acetylhexosaminidase (EC 3.2.1.52); α-L-arabinofuranosidase (EC 3.2.1.55); glucan 1,3-β-glucosidase (EC 3.2.1.58); glucan 1,4-β-glucosidase (EC 3.2.1.74); isoprimeverose-producing oligoxyloglucan hydrolase (EC 3.2.1.120); coniferin β-glucosidase (EC 3.2.1.126); exo-1,3-1,4-glucanase (EC 3.2.1.-); β-N-acetylglucosaminide phosphorylases (EC 2.4.1.-)
Mechanism Retaining
Catalytic Nucleophile/BaseAsp (experimental);
Catalytic Proton DonorGlu for hydrolases (experimental); histidine for phosphorylases (experimental)
NoteA recent paper by Macdonald et al. (PMID=25533455) has shown that the enzymes that cleave b-hexosaminides are in fact retaining b-glycoside phosphorylases.
