1,3-beta-galactosyl-N-acetylhexosamine Phosphorylase
In enzymology, a 1,3-beta-galactosyl-N-acetylhexosamine phosphorylase () is an enzyme that catalyzes the chemical reaction :beta-D-galactopyranosyl-(1->3)-N-acetyl-D-glucosamine + phosphate \rightleftharpoons 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 ''N''-Acetylglucosamine (GlcNAc) is an amide derivative of the monosaccharide glucose. It is a secondary amide between glucosamine and acetic acid. It is significant in several biological systems. It is part of a biopolymer in the bacteri .... 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. References * Gene Ontology ...
