CC -!- FUNCTION: Catalyzes the ATP-dependent polymerization of arginine and
CC aspartate to multi-L-arginyl-poly-L-aspartic acid (cyanophycin; a
CC water-insoluble reserve polymer). {ECO:0000256|ARBA:ARBA00003184}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[L-4-(L-arginin-2-N-yl)aspartate](n) + ATP + L-aspartate = [L-
CC 4-(L-arginin-2-N-yl)aspartate](n)-L-aspartate + ADP + H(+) +
CC phosphate; Xref=Rhea:RHEA:13277, Rhea:RHEA-COMP:13728, Rhea:RHEA-

CC Evidence={ECO:0000256|ARBA:ARBA00000917};
CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC {ECO:0000256|ARBA:ARBA00004752}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the MurCDEF family.
CC {ECO:0000256|ARBA:ARBA00009060}.
