EC 2.4.1.211

Accepted name: 1,3-β-galactosyl-N-acetylhexosamine phosphorylase

Reaction: β-D-galactopyranosyl-(1→3)-N-acetyl-D-glucosamine + phosphate = α-D-galactopyranose 1-phosphate + N-acetyl-D-glucosamine

Other name(s): lacto-N-biose phosphorylase; LNBP; galacto-N-biose phosphorylase

Systematic name: β-D-galactopyranosyl-(1→3)-N-acetyl-D-hexosamine:phosphate galactosyltransferase

Comments: Reaction also occurs with β-D-galactopyranosyl-(1→3)-N-acetyl-D-galactosamine as the substrate, giving N-acetyl-D-galactosamine as the product.
