| Accepted name: |
UDP-Gal:α-D-GlcNAc-diphosphoundecaprenol α-1,3-galactosyltransferase |
| Reaction: |
UDP-α-D-galactose + N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol = UDP + α-D-Gal-(1→3)-α-D-GlcNAc-diphospho-ditrans,octacis-undecaprenol |
| Other name(s): |
wclR (gene name) |
| Systematic name: |
UDP-α-D-galactose:N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol 3-α-galactosyltransferase (configuration-retaining) |
| Comments: |
The enzyme is involved in the the biosynthesis of the O-antigen repeating unit of Escherichia coli O3. Requires a divalent metal ion (Mn2+, Mg2+ or Fe2+). cf. EC 2.4.1.303, UDP-Gal:α-D-GlcNAc-diphosphoundecaprenol β-1,3-galactosyltransferase. |
