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 MurT subunit catalyzes the ATP-dependent amidation of D-
CC glutamate residue of lipid II, converting it to an isoglutamine
CC residue. {ECO:0000256|HAMAP-Rule:MF_02214}.
CC -!- CATALYTIC ACTIVITY:

CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_02214}.
CC -!- SUBUNIT: Forms a heterodimer with GatD. {ECO:0000256|HAMAP-
CC Rule:MF_02214}.
CC -!- SIMILARITY: Belongs to the MurCDEF family. MurT subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_02214}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02214}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
