A new method is provided to produce O-glycosylated amino acids, O-glycosylated peptides or derivatives of these. The method involves at least one reaction where an alpha -saccharide or an alpha -glycoside of Ga1NAc is used as glycosyl donor and a derivative of serine or threonine is used as acceptor in a transglycosylation reaction with N-acetyl- alpha -D-galactosaminidase as the catalyst.
