CC -!- FUNCTION: Exopeptidase that catalyzes the hydrolytic cleavage of multi-
CC L-arginyl-poly-L-aspartic acid (cyanophycin; a water-insoluble reserve
CC polymer) into aspartate-arginine dipeptides.
CC {ECO:0000256|ARBA:ARBA00002039}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[L-4-(L-arginin-2-N-yl)aspartate](n) + H2O = [L-4-(L-arginin-
CC 2-N-yl)aspartate](n-1) + L-4-(L-arginin-2-N-yl)aspartate;
CC Xref=Rhea:RHEA:12845, Rhea:RHEA-COMP:13728, Rhea:RHEA-COMP:13734,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:137986, ChEBI:CHEBI:137991;
CC EC=3.4.15.6; Evidence={ECO:0000256|ARBA:ARBA00001092};
CC -!- SIMILARITY: Belongs to the peptidase S51 family.
CC {ECO:0000256|ARBA:ARBA00006534}.
