Abstract

CoA-transferases are found in organisms from all kingdoms of life. They catalyse reversible transfer reactions of coenzyme A groups from CoA-thioesters to free acids. There are at least three families of CoA-transferases, which differ in sequence and reaction mechanism:

  • Family I consists of CoA-transferases for 3-oxoacids , short-chain fatty acids and glutaconate . Most use succinyl-CoA or acetyl-CoA as CoA donors.
  • Family II consists of the homodimeric alpha-subunits of citrate lyase and citramalate lyase . These enzymes catalyse the transfer of acyl carrier protein (ACP) with a covalently bound CoA derivative, but can accept free CoA thioesters as well.
  • Family III consists of formyl-CoA:oxalate CoA-transferase [PubMed15213226], succinyl-CoA:(R)-benzylsuccinate CoA-transferase [PubMed11418570], (E)-cinnamoyl-CoA:(R)-phenyllactate CoA-transferase [PubMed10849007], and butyrobetainyl-CoA:(R)-carnitine CoA-transferase [PubMed15823031]. These CoA-transferases occur in prokaryotes and eukaryotes, and catalyse CoA-transfer reactions in a highly substrate- and stereo-specific manner [PubMed11749953].

This entry represents family III CoA-transferases.

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 7 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 CoA-transferase family III (CaiB/BaiF) 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 7 hidden Markov models representing the CoA-transferase family III (CaiB/BaiF) superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
