doxD

Gene
doxD
Protein
Naphthalene 1,2-dioxygenase system, small oxygenase component
Organism
Pseudomonas sp. (strain C18)
Length
194 amino acids
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 beta subunit seems to have a structural role in the holoenzyme.
Similarity
Belongs to the bacterial ring-hydroxylating dioxygenase beta subunit family.

Protein
Thiosulfate dehydrogenase [quinone] large subunit
Organism
Acidianus ambivalens
Length
184 amino acids
Function
TQO plays a role in sulfur oxidation and is proposed to couple sulfur oxidation to dioxygen reduction; caldariellaquinone or sulfolobus quinone seem to serve to transfer electrons to the electron transport chain terminal oxidase formed by DoxBCE.
