  • Title: Activation of 3-methyl-branched fatty acids in rat liver.
    Author: Vanhooren JC, Asselberghs S, Eyssen HJ, Mannaerts GP, Van Veldhoven PP.
    Journal: Int J Biochem; 1994 Sep; 26(9):1095-101. PubMed ID: 7988734.
    Abstract:
    1. Subcellular fractionation of rat liver revealed that 3-methylmargaric acid, a monobranched phytanic acid analogue, can be activated by mitochondria, endoplasmic reticulum and peroxisomes. 2. Indirect data (effects of pyrophosphate and Triton X-100) suggested that the peroxisomal activation of 3-methylmargaric, 2-methylpalmitic and palmitic acid is catalyzed by different enzymes. 3. Despite many attempts, column chromatography of solubilized peroxisomal membrane proteins so far did not provide more conclusive data. On various matrices, lignoceroyl-CoA synthetase clearly eluted differently from the synthetases acting on 3-methylmargaric, 2-methylpalmitic and palmitic acid. The latter three however, tended to coelute together, although often not in an identical manner.
