Abstract

Dimeric alpha-beta barrel domains exhibit an alpha+beta sandwich fold with an antiparallel beta sheet that forms a closed barrel. These domains dimerise through the beta-sheet, and in some cases these dimers may assemble into higher oligomers. Domains with this structure are found in proteins from several different families, including bacterial actinorhodin biosynthesis monooxygenase (ActVa-Orf6), which catalyses the oxidation of an aromatic intermediate of the actinorhodin biosynthetic pathway [PubMed12514126]; bacterial muconalactone isomerase, a decamer composed of five dimers [PubMed2926818]; and the C-terminal domain of archaeal LprA, a member of the Lrp/AqsnC family of transcription regulators [PubMed11230123].

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 41 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 Dimeric alpha+beta barrel 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 41 hidden Markov models representing the Dimeric alpha+beta barrel superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
