N acetylglucosaminyl diphospho decaprenol L rhamnosyltransferase

N-acetylglucosaminyl-diphospho-decaprenol L-rhamnosyltransferase (EC 2.4.1.289, WbbL) is an enzyme with systematic name dTDP-6-deoxy-beta-L-mannose:N-acetyl-alpha-D-glucosaminyl-diphospho-trans,octacis-decaprenol 3-alpha-L-rhamnosyltransferase. This enzyme catalyses the following chemical reaction

dTDP-6-deoxy-beta-L-mannose + N-acetyl-alpha-D-glucosaminyl-diphospho-trans,octacis-decaprenol ⇌ dTDP + alpha-L-rhamnopyranosyl-(1->3)-N-acetyl-alpha-D-glucosaminyl-diphospho-trans,octacis-decaprenol

This enzyme requires Mn²⁺ or Mg²⁺.
