Also known as creatine amidinohydrolase

In enzymology, creatinase (), also known as creatine amidinohydrolase, is classified as a hydrolase enzyme, acting on carbon-nitrogen bonds in linear amidines. Specifically, this enzyme breaks the amidino C-N bond in creatine, producing sarcosine and urea. Creatinase activity has been described in several bacteria species, most notably Pseudomonas putida, where the enzyme plays a key role in the metabolism of creatine as a nitrogen and carbon source.
