CC   -!- FUNCTION: Catalyzes the non-heme iron(II)-dependent oxidative
CC       cleavage of 2,3-dihydroxyphenylpropionic acid and 2,3-
CC       dihydroxicinnamic acid into 2-hydroxy-6-ketononadienedioate and 2-
CC       hydroxy-6-ketononatrienedioate, respectively (By similarity).
CC   -!- CATALYTIC ACTIVITY: 3-(2,3-dihydroxyphenyl)propanoate + O(2) = 2-
CC       hydroxy-6-oxonona-2,4-diene-1,9-dioate.
CC   -!- CATALYTIC ACTIVITY: 2,3-dihydroxicinnamic acid + O(2) = 2-hydroxy-
CC       6-oxonona-2,4,7-triene-1,9-dioate.
CC   -!- COFACTOR: Fe(2+) ion (By similarity).
CC   -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropionic acid
CC       degradation.
CC   -!- SUBUNIT: Homotetramer (By similarity).
CC   -!- SIMILARITY: Belongs to the ligB/mhpB extradiol dioxygenase family.
