Comments
[?]
| FUNCTION | The lipid II isoglutaminyl synthase complex catalyzes the formation of alpha-D-isoglutamine in the cell wall lipid II stem peptide. The MurT subunit catalyzes the ATP-dependent amidation of D- glutamate residue of lipid II, converting it to an isoglutamine residue. |
| CATALYTIC ACTIVITY | Reaction=ATP + beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys- D-Ala-D-Ala)-di-trans,octa-cis-undecaprenyl diphosphate + H2O + L- glutamine = ADP + beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-D- isoglutaminyl-L-Lys-D-Ala-D-Ala)-di-trans,octa-cis-undecaprenyl diphosphate + H(+) + L-glutamate + phosphate; Xref=Rhea:RHEA:57928, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:58359, ChEBI:CHEBI:60033, ChEBI:CHEBI:62233, ChEBI:CHEBI:456216; EC=6.3.5.13; |
