RT   "The lux genes of the luminous bacterial symbiont, Photobacterium
RT   leiognathi, of the ponyfish. Nucleotide sequence, difference in gene

CC   -!- FUNCTION: Light-emitting reaction in luminous bacteria. The
CC       specific role of the beta subunit is unknown, but it is absolutely
CC       required for bioluminescence activity.
CC   -!- CATALYTIC ACTIVITY: RCHO + reduced FMN + O(2) = RCOOH + FMN +
CC       H(2)O + light.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain.
CC   -!- SIMILARITY: Belongs to the bacterial luciferase oxidoreductase
CC       family.
