Alkanal monooxygenase beta chain
EC=1.14.14.3

Alternative name(s):
Bacterial luciferase beta chain

Gene names

Name:

luxB

Organism

Photorhabdus luminescens (Xenorhabdus luminescens)

Taxonomic identifier

29488 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Photorhabdus

Protein attributes

Sequence length	324 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Light-emitting reaction in luminous bacteria. The specific role of the beta subunit is unknown, but it is absolutely required for bioluminescence activity.
Catalytic activity	RCHO + reduced FMN + O2 = RCOOH + FMN + H2O + light.
Subunit structure	Heterodimer of an alpha and a beta chain.
Sequence similarities	Belongs to the bacterial luciferase oxidoreductase family.
