The enzyme 4-(2-carboxyphenyl)-2-oxobut-3-enoate aldolase (EC 4.1.2.34) catalyzes the chemical reaction

(3Z)-4-(2-carboxyphenyl)-2-oxobut-3-enoic acid
 
H2O
 
 
 
 
+
 

This enzyme participates in phenanthrene degradation. Its substrate is produced from 1-hydroxy-2-naphthoic acid by the enzyme 1-hydroxy-2-naphthoate 1,2-dioxygenase.[1][2]

Nomenclature

This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is (3Z)-4-(2-carboxyphenyl)-2-oxobut-3-enoate 2-formylbenzoate-lyase (pyruvate-forming). Other names in common use include 2'-carboxybenzalpyruvate aldolase, (3E)-4-(2-carboxyphenyl)-2-oxobut-3-enoate, 2-carboxybenzaldehyde-lyase, and (3Z)-4-(2-carboxyphenyl)-2-oxobut-3-enoate 2-formylbenzoate-lyase.[1]
