CC -!- FUNCTION: The lipid II isoglutaminyl synthase complex catalyzes the
CC formation of alpha-D-isoglutamine in the cell wall lipid II stem
CC peptide. The GatD subunit catalyzes the hydrolysis of glutamine to
CC glutamate and ammonia. The resulting ammonia molecule is channeled to
CC the active site of MurT. {ECO:0000256|HAMAP-Rule:MF_02213}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-
CC D-Ala-D-Ala)-di-trans,octa-cis-undecaprenyl diphosphate + H2O + L-
CC glutamine = ADP + beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-D-
CC isoglutaminyl-L-Lys-D-Ala-D-Ala)-di-trans,octa-cis-undecaprenyl
CC diphosphate + H(+) + L-glutamate + phosphate; Xref=Rhea:RHEA:57928,

CC Evidence={ECO:0000256|HAMAP-Rule:MF_02213};
CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_02213}.
CC -!- SUBUNIT: Forms a heterodimer with MurT. {ECO:0000256|HAMAP-
CC Rule:MF_02213}.
CC -!- SIMILARITY: Belongs to the CobB/CobQ family. GatD subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_02213}.
