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:
