Protein

Alkanal monooxygenase beta chain

Gene

luxB

Organism
Vibrio harveyi (Beneckea harveyi)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Light-emitting reaction in luminous bacteria. The specific role of the beta subunit is unknown, but it is absolutely required for bioluminescence activity.By similarity

Catalytic activityi

A long-chain aldehyde + FMNH2 + O2 = a long-chain fatty acid + FMN + H2O + light.By similarity
