Abstract
Through the use of Capsicum chromoplast membranes, we report for the first time the direct methylation of γ-tocopherol into α-tocopherol in the presence of S-adenosylmethionine. Furthermore the S-adenosylmethionine: γ-tocopherol methyltransferase activity has been solubilized. On a protein basis, the activity recovered in the soluble preparation was higher than that bound to the membranes.
摘要
通过使用辣椒质体膜，我们首次报道了在 S-腺苷甲硫氨酸存在的情况下，γ-生育酚直接甲基化为α-生育酚。此外，S-腺苷甲硫氨酸：γ-生育酚甲基转移酶活性已被溶解。在蛋白质基础上，可溶性制剂中回收的活性高于与膜结合的活性。
