cyanophycin synthase (L-arginine-adding) EC#: 6.3.2.30; ChemWhat Code: 1383766

Product Name cyanophycin synthase (L-arginine-adding)
Example Structure Example Structure of cyanophycin synthase (L-arginine-adding) EC#: 6.3.2.30
Synonyms Ava_0335, CGP synthetase, CphA, CphA1, CphA2, CphA49, CphANE1, cyanophycin synthetase, More, Tlr2170 protein
EC Number 6.3.2.30
CAS Registry Number 131554-17-1
Comments Requires Mg2+?for activity. Both this enzyme and EC?6.3.2.29, cyanophycin synthase (L-aspartate-adding), are required for the elongation of cyanophycin, which is a protein-like cell inclusion that is unique to cyanobacteria and acts as a temporary nitrogen store [2]. Both enzymes are found in the same protein but have different active sites [2]. Both?L-Asp and?L-Arg must be present before either enzyme will display significant activity [2]. Canavanine and lysine can be incoporated into the polymer instead of arginine [2].
Cofactor Mg2+
History
Reactions Atp + (L-Asp(4-L-Arg))(n)-L-Asp + L-Arg = adp + phosphate + (L-Asp(4-L- Arg))(n+1).
