tol 2,4-cyclodiphosphate (1) into a phosphorylated derivative of (E)-2-methylbut-2-ene-1,4-diol (6), which most probably represents a novel intermediate in the methylerythritol phosphate pathway for isoprenoid biosynthesis. The free diol 6 was accumulated by phosphatase treatment of the crude enzyme preparation and was identified by comparison with a synthetic reference.
从A粗无细胞系统大肠埃希氏杆菌菌株过表达含有三个基因簇yfgA,yfgB和gcpE转换的2- Ç甲基d赤藓糖醇2,4-环(1)到的磷酸化衍生物(É) -2-甲基丁-2-烯-1,4-二醇(6),最有可能代表用于异戊二烯生物合成的甲基赤藓糖醇磷酸途径中的新型中间体。通过粗酶制剂的磷酸酶处理来积累游离二醇6,并通过与合成参考物进行比较来鉴定。
