In [[Biology:Enzymology|enzymology]], a '''3-carboxyethylcatechol 2,3-dioxygenase''' ({{EC number|1.13.11.16}}) is an [[Biology:Enzyme|enzyme]] that [[Chemistry:Catalysis|catalyzes]] the [[Chemistry:Chemical reaction|chemical reaction]]

:3-(2,3-dihydroxyphenyl)propanoate + O<sub>2</sub> <math>\rightleftharpoons</math> 2-hydroxy-6-oxonona-2,4-diene-1,9-dioate

Thus, the two [[Biology:Substrate (biochemistry)|substrates]] of this enzyme are 3-(2,3-dihydroxyphenyl)propanoate and [[Chemistry:Oxygen|O<sub>2</sub>]], whereas its [[Chemistry:Product|product]] is 2-hydroxy-6-oxonona-2,4-diene-1,9-dioate.

This enzyme belongs to the family of [[Biology:Oxidoreductase|oxidoreductase]]s, specifically those acting on single donors with O<sub>2</sub> as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O<sub>2</sub>.  The [[Biology:List of enzymes|systematic name]] of this enzyme class is '''3-(2,3-dihydroxyphenyl)propanoate:oxygen 1,2-oxidoreductase (decyclizing)'''. Other names in common use include '''2,3-dihydroxy-beta-phenylpropionic dioxygenase''', '''2,3-dihydroxy-beta-phenylpropionate oxygenase''', and '''3-(2,3-dihydroxyphenyl)propanoate:oxygen 1,2-oxidoreductase'''.  This enzyme participates in phenylalanine metabolism.  It employs one [[Biology:Cofactor (biochemistry)|cofactor]], [[Chemistry:Iron|iron]].
