摘要

1.1. 大鼠肝脏亚细胞分离表明,单支植酸类似物3-甲基人造黄油酸可被线粒体、内质网和过氧化物酶体激活。间接数据(焦磷酸盐和Triton X-100的影响)表明,3-甲基人造脂、2-甲基棕榈酸和棕榈酸的过氧化物酶体活化是由不同的酶催化的。尽管进行了许多尝试,但溶化过氧化物酶体膜蛋白的柱层析迄今尚未提供更确凿的数据。在不同基质上,木酰辅酶a合成酶与作用于3-甲基人造黄油、2-甲基棕榈酸和棕榈酸的合成酶洗脱明显不同。然而,后三者倾向于一起吸取,尽管往往不是以相同的方式。

Activation of 3-methyl-branched fatty acids in rat liver

  • 1.

    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.

    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.

    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.
