| Mechanism | Retaining |
| Catalytic Nucleophile/Base | Asp (experimental); |
| Catalytic Proton Donor | Glu for hydrolases (experimental); histidine for phosphorylases (experimental) |
| Note | A recent paper by Macdonald et al. (PMID=25533455) has shown that the enzymes that cleave b-hexosaminides are in fact retaining b-glycoside phosphorylases. |
