Substrate specificities
Gal-beta-1,3-GalNAc-alpha-R O-linked glycans on proteins
Kinetics and Mechanism
Retaining mechanism determined by H1-NMR with the BlGH101 enzyme. PMID: 16141207
Catalytic Residues
Using the enzyme from Streptococcus pnuemoniae the nucleophile was determined as residue D764. Willis et al in preparation The acid/base catalyst in SpGH101 was determined to be E796.
