Glycoside Hydrolase Family 149

Activities in Familyβ-1,3-glucan phosphorylase (EC 2.4.1.97)
Mechanism inverting
ClanGH-Q
3D Structure Status( α / α ) 6 (inferred)
Catalytic Nucleophile/Basephosphate
Catalytic Proton DonorAsp (inferred)
NoteFamily created after Kuhaudomlarp et al. J. Biol. Chem. (2018) [PMID=29317507] who have shown that the Euglena gracilis enzyme is a b-1,3-glucan phosphorylase. Distant sequence similarities suggest this family forms clan GH-Q with family GH94.
