| 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. |
