UDP-MurAc(oyl-L-Ala-γ-D-Glu-L-Lys-D-Ala-D-Ala):undecaprenyl-phosphate phospho-N-acetylmuramoyl-pentapeptide-transferase



In Gram-negative and some Gram-positive organisms the L-lysine is replaced by meso-2,6-diaminoheptanedioate (meso-2,6-diaminopimelate, A2pm), which is combined with adjacent residues through its L-centre. The undecaprenol involved is ditrans,octacis-undecaprenol.
