  Enzymatic synthesis of β-galactosyldipeptides and of β-1,3-digalactosylserine derivatives using β-galactosidase

  摘要：

  The transgalactosidation from lactose to dipeptides has been achieved using beta-galactosidase from E. Coli as catalyst. Two series of dipeptides have been studied, each of them containing a serine residue. The best condensations occur when serine is at the N-terminal end of the dipeptide. Mild hydrolysis of the ester group of the labile glycosyl-dipeptide derivatives has been achieved using subtilisin. We also describe the condensation of lactose with beta-galactosyl serine to give beta-1,3-digalactosyl-serine derivatives.

  Disaccharide-peptide conjugates were obtained in yields of 30-50% from o-nitrophenyl beta-D-galactopyranoside by employing beta-D-galactosidase from E. coli as catalyst. Two series of beta-D-galactosyldipeptides were examined as galactosyl acceptors. They both contain an L-serine residue beta-linked to the anomeric carbon of galactose. In the first series, serine is in the N-terminal position of the dipeptide; in the second series, serine is in the C-terminal position. The second amino acid is L-alanine or glycine. Some of our substrates gave a high yield of beta(1 --> 3)-digalactosyldipeptide derivatives and all gave very little of the beta-(1 --> 6) regioisomer. The conditions and the limitations of the transgalactosylation reaction are discussed.
