ENZYME entry: EC 2.4.1.341

Accepted Name
alpha-1,2-colitosyltransferase
Reaction catalysed
beta-D-galactosyl-(1->3)-N-acetyl-D-glucosamine + GDP-beta-L-colitose <=> alpha-L-colitosyl-(1->2)-beta-D-galactosyl-(1->3)-N-acetyl-D-glucosamine + GDP + H(+)
Comment(s)
  • The enzyme, characterized from the bacterium Escherichia coli O55:H7, participates in the biosynthesis of an O-antigen.
  • The reaction involves anomeric inversion, and does not require any metal ions.
  • The enzyme is highly specific toward the acceptor, exclusively recognizing lacto-N-biose, but can accept GDP-L-fucose as the donor with almost the same activity as with GDP-beta-L-colitose.
