1) Transfer GalNAc to the Glc-Glc-GlcNAc modified Fap1.
Additional Information
1) dGT1 is involved in the biosynthesis of an SRRP adhesin Fap1 of S. parasanguinis. 2) dGT1 is unique bifunctional protein contains an N-terminal unknown function domain (DUF1792) a new type of glycosyltransferases, transferring glucose residues to Glc-GlcNAc-Fap1, and that the C terminus domain (CgT) is an independent glycosyltransferase and important for Fap1 glycosylation it transfers GlcNAc to the Glc-Glc-GlcNAc-modified Fap1.
