标题:黄曲霉紧密相关的baeyer-Villiger单加氧酶之间的功能差异
摘要:Baeyer-Villiger单加氧酶(bvmo)催化将酮化学,区域和对映选择性氧化为酯和内酯.迄今为止,尽管已经经常证明使用真菌进行的拜耳-维利格氧化作用,但是大多数可用的克隆bvmos都来自细菌.在这里,我们报告从真菌黄曲霉的四个bvmos的克隆和表征nrrl3357.系统发育分析表明,这四个bvmo与其他特征明确的bvmo包括一个明显的组聚在一起,包括环己酮,苯丙酮和4-羟基苯乙酮单加氧酶.在bvmo的grogan分类/聚类的基础上,我们将bvmo的这一新组指定为vi组.vi组bvmo显示出与环戊酮单加氧酶(cpmo)型bvmo(i组)的早期差异.使用环状,双环,脂肪族和芳基酮进行的底物分析显示,不仅在这组新的bvmo与cpmo型bvmo之间,而且在四个黄曲霉之间,在功能和特异性上也存在明显的差异.bvmo旁系同源物,尽管它们具有很高的序列相似性.这项研究不仅有助于增加可用bvm

标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.
