What is "phthalyl amidase"

n. (context biochemistry English) A hydrolase enzyme that catalyzes the chemical reaction from phthalylamide and water into phthalic acid and substituted amine.

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

a phthalylamide + HO $\rightleftharpoons$ phthalic acid + a substituted amine

Thus, the two substrates of this enzyme are phthalylamide and HO, whereas its two products are phthalic acid and substituted amine.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is phthalyl-amide amidohydrolase.
