Protein
Alkanal monooxygenase beta chain
Gene
luxB
Organism
Photorhabdus luminescens (Xenorhabdus luminescens)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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

Catalytic activityi

RCHO + reduced FMN + O2 = RCOOH + FMN + H2O + light.
