Mechanism	Inverting e
Clan	GH-Q
3D Structure Status	( α / α ) 6 barrel (inferred)
Catalytic Nucleophile/Base	phosphate
Catalytic Proton Donor	Asp (inferred)
Note	Family 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.
