1-aminocyclopropane-1-carboxylate deaminase

1-aminocyclopropane-1-carboxylate deaminase

In enzymology, a 1-aminocyclopropane-1-carboxylate deaminase (EC number| is an enzyme that catalyzes the chemical reaction

:1-aminocyclopropane-1-carboxylate + H2O ightleftharpoons 2-oxobutanoate + NH3

Thus, the two substrates of this enzyme are 1-aminocyclopropane-1-carboxylate and H2O, whereas its two products are 2-oxobutanoate and NH3.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in compounds that have not been otherwise categorized within EC number 3.5. The systematic name of this enzyme class is 1-aminocyclopropane-1-carboxylate aminohydrolase (isomerizing). This enzyme is also called 1-aminocyclopropane-1-carboxylate endolyase (deaminating). This enzyme participates in propanoate metabolism. It employs one cofactor, pyridoxal phosphate.
