Bacterial luciferase is a flavin monooxygenase that catalyses the oxidation of long-chain aldehydes and releases energy in the form of visible light, and which uses flavin as a substrate rather than a cofactor [PubMed8703001]. Bacterial luciferase is an alpha/beta (LuxA/LuxB) heterodimer, where each individual subunit folds into a single TIM (beta/alpha)8-barrel domain. There are structural similarities between bacterial luciferase and nonfluorescent flavoproteins (LuxF, FP390), alkanesulphonate monooxygenase (SsuD), and coenzyme F420-dependent terahydromethanopterin reductase, which make up clearly related families with somewhat different folds [PubMed7776372, PubMed12445781, PubMed10891279].

More information about these proteins can be found at Protein of the Month: Luciferase.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 9 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a Bacterial luciferase-like domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 9 hidden Markov models representing the Bacterial luciferase-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
