A particulate enzyme from Phaseolus aureus seedlings catalyses the incorporation of radioactivity from S-adenosyl[Me-(14)C]methionine into several lipid acceptors present in the enzyme preparation. The structure of one of the radioactive lipids has been elucidated by using mass, n.m.r. and i.r. spectral data. This compound has a molecular formula C(28)H(57)OH, is a saturated primary alcohol and has a single branch of one methyl group in the interior of the hydrocarbon chain. The results of a Kuhn-Roth degradation demonstrate that the branch methyl group is the one derived from S-adenosylmethionine.
来自金甲豆幼苗的一种颗粒酶催化将S-腺苷[甲基-(14)C]甲硫氨酸中的放射性掺入酶制剂中存在的几种脂质受体。通过使用质谱、核磁共振和红外光谱数据阐明了其中一种放射性脂质的结构。该化合物的分子式为C(28)H(57)OH,是一种饱和伯醇,在烃链内部有一个单甲基分支。库恩-罗思降解的结果表明,分支甲基是源自S-腺苷甲硫氨酸的甲基。
