FUNCTION: Catalyzes the non-heme iron(II)-dependent oxidative cleavage of 2,3-dihydroxyphenylpropionic acid and 2,3-dihydroxicinnamic acid into 2-hydroxy-6-ketononadienedioate and 2-hydroxy-6-ketononatrienedioate, respectively (By similarity).
CATALYTIC ACTIVITY: 3-(2,3-dihydroxyphenyl)propanoate + O₂ = 2-hydroxy-6-oxonona-2,4-diene-1,9-dioate.
CATALYTIC ACTIVITY: 2,3-dihydroxicinnamic acid + O₂ = 2-hydroxy-6-oxonona-2,4,7-triene-1,9-dioate.
COFACTOR: Fe(2+) ion (By similarity).
PATHWAY: Aromatic compound metabolism; 3-phenylpropionic acid degradation .
SUBUNIT: Homotetramer (By similarity).
SIMILARITY: Belongs to the ligB/mhpB extradiol dioxygenase family.
