UDP-N-acetylgalactosamine diphosphorylase (EC 2.7.7.83) is an enzyme with systematic name UTP:N-acetyl-alpha-D-galactosamine-1-phosphate uridylyltransferase.[1][2] This enzyme catalyses the following chemical reaction
- UTP + N-acetyl-alpha-D-galactosamine 1-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] diphosphate + UDP-N-acetyl-alpha-D-galactosamine
The enzyme from plants and animals also acts on N-acetyl-alpha-D-glucosamine 1-phosphate.
