http://purl.uniprot.org/citations/2365812http://www.w3.org/2000/01/rdf-schema#comment"The rhizomelic form of chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized biochemically by an impairment of plasmalogen biosynthesis and phytanate catabolism. We have now found that the maturation of peroxisomal 3-oxoacyl-CoA thiolase is impaired in fibroblasts from RCDP patients. To establish the subcellular localization of the 3-oxoacyl-CoA thiolase precursor protein, cultured skin fibroblasts were fractionated on a continuous Nycodenz gradient. Only a small amount of 3-oxoacyl-CoA thiolase activity was present in the catalase-containing (peroxisomal) fractions of RCDP fibroblasts in comparison with control fibroblasts. Moreover, the amount of thiolase protein in immunoblots of the catalase-containing fractions was below the limit of detection. Finally, the beta-oxidation of [14C]palmitoyl-CoA was found to be reduced in these fractions. We conclude that the mutation in RCDP leads to a partial deficiency of 3-oxoacyl-CoA thiolase activity in the peroxisomes and, concomitantly, an impairment in the ability to convert the precursor of this protein to the mature form. The reduction of 3-oxoacyl-CoA thiolase activity results in a decrease in the rate of peroxisomal beta-oxidation of palmitoyl-CoA. However, the capacity of the peroxisomes to oxidize very-long-chain fatty acids must be sufficient to prevent excessive accumulation of these compounds in vivo."xsd:string
