"Extracellular a-N-acetylgalactosaminidase from Aspergillus niger catalyzed glycosylation yielding a series of 2-acetamido-2-deoxy-a-D-galactobiosides using 2-acetamido-2-deoxy-D-galactopyranose as a glycosyl donor. The isomers a-D-GalpNAc-D-GalpNAc, a-D-GalpNAc-D-GalpNAc and a-D-GalpNAc-D-GalfNAc were isolated and spectrally characterized. The purified enzyme was further used for the glycosylation of free amino acids (serine and threonine) and their N-(tert-butoxycarbonyl)-protected analogs to synthesize the Tn antigen (GalpNAc-a-O-Ser/Thr) and its N-(tertbutoxycarbonyl)-protected derivatives" .
