oxidoreductase from Talaromyces islandicus WF-38-12 has been identified through genome analysis. It has been shown to catalyze a regio- and stereoselective reduction of anthrols (formed in situ by the reduction of anthraquinones in the presence of Na2S2O4) to (R)-dihydroanthracenones, with high enantiomeric excess (>99%). The implications of results on the biosynthesis of deoxygenated (bis)anthraquinones and
通过基因组分析已经鉴定了来自岛形Talaromyces islandicus WF-38-12的NADPH依赖性氧化还原酶。已显示其催化对映异构和立体选择性的蒽还原反应(对映异构体过量(> 99%))(在Na 2 S 2 O 4存在下通过蒽醌还原原位形成)变为(R)-二氢蒽酮。。讨论了结果对脱氧(双)蒽醌和改性(双)蒽醌的生物合成的影响。

The regio- and stereospecificity of incorporation of label from [2H3] acetate into scytalone, a dihydronaphthalene metabolite of Phialaphora lagerbergii, has been determined by high field 1H and 2H NMR studies. Incorporation studies with [2-13C] malonate have failed to reveal an acetate “starter” effect suggesting that scytalone may be derived from a hexaketide precursor rather than a pentaketide as
标签的掺入从[的区域选择性和立体定向性2 ħ 3 ]乙酸甲酯进小柱孢酮,的二氢萘代谢物Phialaphora lagerbergii,已由高场确定1 H和2个1 H NMR研究。与掺入研究[2- 13 C]丙二酸二乙酯未能揭示乙酸盐“起动器”的效果表明小柱孢酮可以从hexaketide前体,而不是如pentaketide以前提出来导出。
