- 1,4-diguanidinobutane + H2O agmatine + urea
Thus, the two substrates of this enzyme are 1,4-diguanidinobutane and H2O, whereas its two products are agmatine 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 1,4-diguanidinobutane amidinohydrolase.
