Cyanophycin synthase (L-aspartate-adding)

Cyanophycin synthase (L-aspartate-adding) (EC 6.3.2.29, CphA, CphA1, CphA2, cyanophycin synthetase, multi-L-arginyl-poly-L-aspartate synthase) is an enzyme with systematic name cyanophycin:L-aspartate ligase (ADP-forming).

[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction This enzyme requires Mg2+ for activity.

All enzymes known to have this activity also catalyze the addition of arginine, i.e. cyanophycin synthase (L-arginine-adding) activity.

It is structurally similar to Muramyl ligases.
