HHsearch alignment for GI: 254781054 and conserved domain: TIGR02428
>TIGR02428 pcaJ_scoB_fam 3-oxoacid CoA-transferase, B subunit; InterPro: IPR012791 CoA-transferases catalyse the reversible transfer of of coenzyme A from CoA-thioesters to free acids, and can be divided into three families . Family I includes transferases for 3-oxoacids (2.8.3.5 from EC, 2.8.3.6 from EC), short-chain fatty acids (2.8.3.8 from EC, 2.8.3.9 from EC) and glutaconate (2.8.3.12 from EC). Most of the family I enzymes use acetyl-CoA or succinyl-CoA as CoA donors, and are composed of two separate polypeptides, subunits A and B, which generally aggregate as heterodimers or heterotetramers. The eukaryotic enzymes, however, are generally composed of a single two-domain polypetide representing a fusion of the A and B subunits. The transfer of CoA from one substrate to another occurs via a ping pong mechanism which involves the formation of thioester bond between CoA and a conserved glutamate residue at the active site of the enzyme . This entry represents the B subunit of family I CoA-transferases, which contains the conserved active-site glutamate residue. This domain forms a three-layer alpha-beta-alpha sandwich where the central layer is a mixed beta-sheet, against which helices pack from both sides , . The active site is thought to be located at the interface of the A and B subunits and formed by loops from both subunits.; GO: 0008410 CoA-transferase activity.
