UDP-N-Acetylmuramoylpentapeptide-Lysine N6-Alanyltransferase Activity

Uridine Diphosphoacetylmuramoylpentapeptide Lysine N(6)-Alanyltransferase Activity

Catalysis of the reaction: UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine + L-alanyl-tRNA = UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-N6-(L-alanyl)-L-lysyl-D-alanyl-D-alanine + tRNA.
