Abstract
- The incorporation of [2-(14)C]mevalonic acid by Chloropseudomonas ethylica strain 2K into chlorobactene was studied. 2. Oxidative degradation of chlorobactene of constant specific radioactivity produced labelled benzenecarboxylic acids and indicated that the benzene ring originates from mevalonic acid. 3. Decarboxylation studies demonstrated a stereospecific methyl migration in the formation of the 1,2,5-trimethylphenyl group of chlorobactene. The migrating methyl group was derived from the C-3' position of mevalonic acid.
摘要
- 研究了嗜氯假单胞菌2K菌株将[2-(14)C]甲羟戊酸掺入到氯菌烯中的情况。2. 对具有恒定比放射性的氯菌烯进行氧化降解，产生了标记的苯羧酸，这表明苯环起源于甲羟戊酸。3. 脱羧研究表明，在氯菌烯的1,2,5-三甲基苯基形成过程中存在立体特异性甲基迁移。迁移的甲基来自甲羟戊酸的C-3'位。
