| N-carbamoylsarcosine amidase M-CSA #25 | Carbamoylsarcosine amidohydrolase (CSHase) is involved in one of two alternative creatine degradative pathways in micro-organisms. Both pathways start with creatinine and end with glycine, but the CSHase containing pathway proceeds via N-methylhydantoin, N-carbamoylsarcosine, and sarcosine. | Defined by 5 residues: ASP:A-51LYS:A-144ALA:A-172THR:A-173CYS:A-177 | EC: 3.5.1.59 (PDB Primary Data) |
