Proclavaminate amidinohydrolase

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


 * amidinoproclavaminate + H2O $$\rightleftharpoons$$ proclavaminate + urea

Thus, the two substrates of this enzyme are amidinoproclavaminate and H2O, whereas its two products are proclavaminate 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 amidinoproclavaminate amidinohydrolase. Other names in common use include PAH, and proclavaminate amidino hydrolase. This enzyme participates in clavulanic acid biosynthesis.
