Reaction
ATP + β-D-GlcNAc-(1→4)-Mur2Ac(oyl-L-Ala-γ-D-Glu-L-Lys-D-Ala-D-Ala)-diphospho-ditrans,octacis-undecaprenol + L-glutamine + H2O = ADP + phosphate + β-D-GlcNAc-(1→4)-MurNAc-L-Ala-D-isoglutaminyl-L-Lys-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenol + L-glutamate (overall reaction)
(1a) L-glutamine + H2O = L-glutamate + NH3
(1b) ATP + β-D-GlcNAc-(1→4)-Mur2Ac(oyl-L-Ala-γ-D-Glu-L-Lys-D-Ala-D-Ala)-diphospho-ditrans,octacis-undecaprenol = ADP + β-D-GlcNAc-(1→4)-MurNAc-L-Ala-γ-D-O-P-Glu-L-Lys-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenol
(1c) β-D-GlcNAc-(1→4)-Mur2Ac(oyl-L-Ala-γ-D-O-P-Glu-L-Lys-D-Ala-D-Ala)-diphospho-ditrans,octacis-undecaprenol + NH3 = β-D-GlcNAc-(1→4)-MurNAc-L-Ala-D-isoglutaminyl-L-Lys-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenol + phosphate
Systematic Name
β-D-GlcNAc-(1→4)-Mur2Ac(oyl-L-Ala-γ-D-Glu-L-Lys-D-Ala-D-Ala)-diphospho-ditrans,octacis-undecaprenol:L-glutamine amidoligase (ADP-forming)
Function
The enzyme complex, found in Gram-positive bacteria, consists of two subunits. A glutaminase subunit (cf. EC 3.5.1.2, glutaminase) produces an ammonia molecule that is channeled to a ligase subunit, which adds it to the activated D-glutamate residue of lipid II, converting it to an isoglutamine residue.
Other name
MurT/GatD; MurT/GatD complex
