What is "methylguanidinase"

n. (context enzyme English) A hydrolase enzyme that catalyzes the reaction of methylguanidine and water into methylamine and urea.

In enzymology, a methylguanidinase is an enzyme that catalyzes the chemical reaction

methylguanidine + HO $\rightleftharpoons$ methylamine + urea

Thus, the two substrates of this enzyme are methylguanidine and HO, whereas its two products are methylamine and urea.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amidines. The systematic name of this enzyme class is methylguanidine amidinohydrolase. This enzyme is also called methylguanidine hydrolase.
