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(+) +
