Chains	Enzyme Name	Description	Catalytic Residues
A	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.
