Abstract

This entry represents a structural motif with a beta/alpha TIM barrel found in several proteins families:

  • Endonuclease IV , an AP (apurinic/apyrimidinic) endonuclease that primes DNA repair synthesis by cleaving the DNA backbone 5' of AP sites [PubMed10458614].
  • L-rhamnose isomerase , a tetramer of four TIM barrels that catalyses the isomerisation between aldoses and ketoses, such as between L-rhamnose and L-rhamnulose [PubMed17141803].
  • Xylose isomerase , which catalyses the first reaction in the catabolism of D-xylose by converting D-xylose to D-xylulose [PubMed16673077].
  • Mannonate dehydratase UxuA, which along with mannonate oxidoreductase converts D-fructuronate to 2-keto-3-deoxy-D-gluconate [PubMed7007313].

These proteins share similar, but not identical, metal-binding sites. In addition, xylose isomerase and L-rhamnose isomerase each have additional alpha-helical domains involved in tetramer formation. This entry differs from IPR012307 in having a wider coverage of TIM-barrel protein families.

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 19 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 Xylose isomerase-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 19 hidden Markov models representing the Xylose isomerase-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
