(3R)-HYDROXYACYL-COA DEHYDROGENASE FRAGMENT OF RAT PEROXISOMAL MULTIFUNCTIONAL ENZYME TYPE 2(3R)-HYDROXYACYL-COA DEHYDROGENASE FRAGMENT OF RAT PEROXISOMAL MULTIFUNCTIONAL ENZYME TYPE 2
Structural highlights
FunctionDHB4_RAT Bifunctional enzyme acting on the peroxisomal beta-oxidation pathway for fatty acids. Catalyzes the formation of 3-ketoacyl-CoA intermediates from both straight-chain and 2-methyl-branched-chain fatty acids. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of (3R)-hydroxyacyl-CoA dehydrogenase of rat peroxisomal multifunctional enzyme type 2 (MFE-2) was solved at 2.38 A resolution. The catalytic entity reveals an alpha/beta short chain alcohol dehydrogenase/reductase (SDR) fold and the conformation of the bound nicotinamide adenine dinucleotide (NAD(+)) found in other SDR enzymes. Of great interest is the separate COOH-terminal domain, which is not seen in other SDR structures. This domain completes the active site cavity of the neighboring monomer and extends dimeric interactions. Peroxisomal diseases that arise because of point mutations in the dehydrogenase-coding region of the MFE-2 gene can be mapped to changes in amino acids involved in NAD(+) binding and protein dimerization.
