CC   -!- FUNCTION: Component of the naphthalene dioxygenase (NDO) multicomponent
CC       enzyme system which catalyzes the incorporation of both atoms of
CC       molecular oxygen into naphthalene to form cis-(1R,2S)-dihydroxy-1,2-
CC       dihydronaphthalene. Functions as an intermediate electron transfer
CC       protein via a specific interaction with iron sulfur protein components
CC       (ISP) (NdoB and NdoC). {ECO:0000250|UniProtKB:P0A185}.
CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC         Evidence={ECO:0000250|UniProtKB:P0A185,
CC         ECO:0000255|PROSITE-ProRule:PRU00628};
CC       Note=Binds 1 [2Fe-2S] cluster per subunit.
CC       {ECO:0000250|UniProtKB:P0A185, ECO:0000255|PROSITE-ProRule:PRU00628};
CC   -!- PATHWAY: Aromatic compound metabolism; naphthalene degradation.
CC       {ECO:0000250|UniProtKB:P0A185}.
CC   -!- SUBUNIT: The naphthalene dioxygenase (NDO) multicomponent enzyme system
CC       is composed of an electron transfer component and a dioxygenase
CC       component (iron sulfur protein (ISP)). The electron transfer component
CC       is composed of a ferredoxin reductase (NdoR) and a ferredoxin (NdoA),
CC       and the dioxygenase component is formed of a heterohexamer (trimer of
CC       heterodimers) of three large alpha subunits (NdoB) and three small beta
CC       subunits (NdoC). {ECO:0000250|UniProtKB:P0A185}.
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase
CC       ferredoxin component family. {ECO:0000305}.
