Synthetic Useful Glyco-Enzymes *
Goals: The project supported by National Institute of General Medical Sciences (U01GM116263) aims to develop facile core synthesis-enzymatic extension strategy to access diverse O-glycans and O-glycopeptides. Enzymes (glycosyltransferases) validated in the synthesis of these complex carbohydrates are summarized here. Most enzymes are derived from bacteria with high expression level and activities.
Galactosyltransferase (GalT)
alpha1-3GalT:
alpha1-4GalT:
beta1-3GalT:
beta1-4GalT:
Fucosyltransferase (FucT)
alpha1-2FucT:
alpha1-3FucT:
alpha1-3/4FucT:
alpha1-6FucT:
N-acetyl-hexosaminyltransferase (HexNAcT, including GalNAcT and GlcNAcT)
alpha1-3GalNAcT:
beta1-3HexNAcT:
beta1-3GalNAcT:
beta1-4GalNAcT:
Sialyltransferase (SiaT)
alpha2-3SiaT:
alpha2-6SiaT:
alpha2-3/8SiaT:
alpha2-8/9SiaT:
