Glycoside Hydrolase Family 161

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. (2019) [PMID=30819804] who have shown that the Paenibacillus polymyxa ATCC 842 and Thermosipho africanus TCF52B enzymes are b-1,3-glucan phosphorylases, distantly related to GH149. Hence this family integrates the clan GH-Q with family GH94 and GH149.
