    Expanding the Substrate Scope of Acyltransferase LovD9 for the Biosynthesis of Statin Analogues
    摘要:
    摘要 本研究通过实验室进化的酰基转移酶 LovD9 对单加林 J 酸的酰化作用,确定了制造他汀类似物的新酰基供体。乙烯基酯和对硝基苯酯已成为 LovD9 催化酰化反应的替代底物。乙烯基酯的产物产率可与α-二甲基丁酰基-S-甲基-3-巯基丙酸酯(DMB-SMMP)(LovD9催化的硫酯)的产物产率一样高,而对硝基苯酯在第一个酰化步骤中的反应活性甚至高于DMB-SMMP,但酰化产物产率却较低。通过量子力学(QM)计算阐明了反应机理。

    Single-step production of the simvastatin precursor monacolin J by engineering of an industrial strain of Aspergillus terreus
    摘要:
    Monacolin J is a key precursor for the synthesis of simvastatin (Zocor), an important drug for treating hypercholesterolemia. Industrially, monacolin J is manufactured through alkaline hydrolysis of lovastatin, a fungal polyketide produced by Aspergillus terreus. Multistep chemical processes for the conversion of lovastatin to simvastatin are laborious, cost expensive and environmentally unfriendly. A biocatalysis process for monacolin J conversion to simvastatin has been developed. However, direct bioproduction of monacolin J has not yet been achieved. Here, we identified a lovastatin hydrolase from Penicillium chrysogenum, which displays a 232-fold higher catalytic efficiency for the in vitro hydrolysis of lovastatin compared to a previously patented hydrolase, but no activity for simvastatin. Furthermore, we showed that an industrial A. terreus strain heterologously expressing this lovastatin hydrolase can produce monacolin J through single-step fermentation with high efficiency, approximately 95% of the biosynthesized lovastatin was hydrolyzed to monacolin J. Our results demonstrate a simple and green technical route for the production of monacolin J, which makes complete bioproduction of the cholesterol-lowering drug simvastatin feasible and promising.

  • Structural insights into the catalytic mechanism of lovastatin hydrolase

    The lovastatin hydrolase PcEST from the fungus Penicillium chrysogenum exhibits enormous potential for industrial-scale applications in single-step production of monacolin J, the key precursor for synthesis of the cholesterol-lowering drug simvastatin. This enzyme specifically and efficiently catalyzes the conversion of lovastatin to monacolin J but cannot hydrolyze simvastatin. Understanding the catalytic
    产自青霉青霉的洛伐他汀解酶PcEST在一步合成莫纳可林J的工业规模应用中显示出巨大的工业潜力,莫纳可林J是合成降胆固醇药物辛伐他汀的关键前体。该酶特异性和有效地催化洛伐他汀向莫纳可林J的转化,但不能辛伐他汀。因此,了解PcEST的催化机理和结构-功能关系对于进一步的洛伐他汀解酶的筛选,工程和商业应用非常重要。在这里,我们解决了四个X射线晶体结构,包括apo PcEST(2.3Å),与莫纳可林J复合的PcEST(2.48Å),与底物类似物辛伐他汀(2.4Å)复合的PcEST,以及灭活的PcEST变体(S57A)洛伐他汀底物(2.3Å)。基于结构的生化分析和诱变分析表明,Ser57(亲核试剂)-Tyr170(通用碱基)-Lys60(通用酸)催化三联体,活性位点周围的氢键网络(Trp344和Tyr127)以及特定的底物结合通道共同决定了PcEST的有效和特异性洛伐他汀解作用。此外,由辛
