Diguanidinobutanase

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


 * 1,4-diguanidinobutane + H2O $$\rightleftharpoons$$ 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.
