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 guanidinoacetate amidinohydrolase. This enzyme is also called glycocyaminase. It employs one cofactor, manganese.
