In enzymology, a 1,3-beta-galactosyl-N-acetylhexosamine phosphorylase (EC 2.4.1.211) is an enzyme that catalyzes the chemical reaction
- beta-D-galactopyranosyl-(1->3)-N-acetyl-D-glucosamine + phosphate [math]\displaystyle{ \rightleftharpoons }[/math] alpha-D-galactopyranose 1-phosphate + N-acetyl-D-glucosamine
Thus, the two substrates of this enzyme are beta-D-galactopyranosyl-(1->3)-N-acetyl-D-glucosamine and phosphate, whereas its two products are alpha-D-galactopyranose 1-phosphate and N-acetyl-D-glucosamine.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is beta-D-galactopyranosyl-(1->3)-N-acetyl-D-hexosamine:phosphate galactosyltransferase.
