The
enzyme aminobenzoate decarboxylase ()
catalyzes
Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...
the
chemical reaction
:4(or 2)-aminobenzoate
aniline + CO
2
Thus, the two
substrates of this enzyme are
4-aminobenzoate and
2-aminobenzoate, whereas its two
products are
aniline and
CO2.
This enzyme belongs to the family of
lyase
In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. ...
s, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The
systematic name of this enzyme class is aminobenzoate carboxy-lyase (aniline-forming). It employs one
cofactor,
pyridoxal phosphate.
