PubMed Abstract: Cyanophycinases are serine protease family enzymes which are required for the metabolism of cyanophycin, the natural polymer multi-L-arginyl-poly(L-aspartic acid). Cyanophycinases degrade cyanophycin to β-Asp-Arg dipeptides, which enables use of this important store of fixed nitrogen.
