Cyanophycinase (EC 3.4.15.6, cyanophycin degrading enzyme, beta-Asp-Arg hydrolysing enzyme, CGPase, CphB, CphE, cyanophycin granule polypeptidase, extracellular CGPase) is an enzyme.[1][2][3] It catalyses the following chemical reaction
- [L-Asp(4-L-Arg)]n + H2O [L-Asp(4-L-Arg)]n-1 + L-Asp(4-L-Arg)
The enzyme is highly specific for the branched polypeptide cyanophycin.
