Protein
Naphthalene 1,2-dioxygenase system, large oxygenase component
Organism
Pseudomonas putida
Function
Component of the naphthalene dioxygenase (NDO) multicomponent enzyme system which catalyzes the incorporation of both atoms of molecular oxygen into naphthalene to form cis-(1R,2S)-dihydroxy-1,2-dihydronaphthalene. The alpha subunit has a catalytic role in the holoenzyme. Also able to catalyze the cis-dihydroxylation of biphenyl and phenanthrene (PubMed:10692370).
Similarity
Belongs to the bacterial ring-hydroxylating dioxygenase alpha subunit family.
