Protein: UDP-N-acetylglucosamine diphosphorylase 1 (EC 2.7.7.23) (N-acetylglucosamine-1-phosphate uridylyltransferase 1) (UDP-N-acetylgalactosamine diphosphorylase 1) (EC 2.7.7.83) (Q940S3)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Uridylyltransferase involved in the biosynthesis of UDP-glucosamine, an essential precursor for glycoprotein and glycolipid synthesis. Can use both UDP-glucosamine and the 4-epimer UDP-galactosamine as substrates, but no other sugars or NTPs. Acts redundantly with GLCNAC1PUT2. Required for gametogenesis and embryo development.
