  化学和生物催化的整合：通过葡萄糖通过葡萄糖从糠醛生产呋喃基乙醇酸

  摘要：

  呋喃基乙醇酸（FA）是一种适合与乳酸共聚的假芳族羟基酸，可以使用Brønsted和Lewis酸催化剂的组合，通过酶促衍生的丙酮酸从葡萄糖中制得。首先将Corcercerone在布朗斯台德酸位点（HCl或含Al的β沸石）上转化为呋喃乙二醛水合物（FH），然后在路易斯酸位点（Sn-β沸石）上将FH转化为FA。使用四氢呋喃（THF）作为溶剂在358 K时，将FH转化为FA的选择性高达12％时高达80％。FH的较高转化率导致FA催化FH降解并随后通过沉积使催化剂失活碳质残留物。失活的催化剂可以通过煅烧再生。可以从10％葡萄糖溶液中使用重组蛋白生产Corcercerone从木腐真菌Phanerochaete chrysosporium BKM-F-1767表达吡喃糖2-氧化酶和醛糖-2-纤维素脱水酶的大肠杆菌菌株。在甲醇/水溶剂中，在具有布朗斯台德和路易斯酸位点的含铝Sn-β沸石上，在甲醇/水溶剂中

  Synthesis of the antibiotic cortalcerone from d-glucose using pyranose 2-oxidase and a novel fungal enzyme, aldos-2-ulose dehydratase

  摘要：

  Using two enzymes purified from the white-Tot fungus, PoLyporus obtusus, 5% solutions Of D-glucose have been quantitatively converted in vitro into D-arabino-hexos-2-ulose (D-glucosone) and subsequently into a compound having antimicrobial activity. The antibiotic has been shown by nuclear magnetic resonance and mass spectroscopy to be chemically identical to a previously described fungal metabolite known as cortalcerone. Based on kinetic analysis of the synthetic process, a pathway for the biosynthesis of cortalcerone is proposed, involving both chemical rearrangement and enzymically catalyzed steps. Two enzymes, pyranose 2-oxidase and a previously uncharacterized D-arabino-hexos-2-ulose-utilizing enzyme, may be sufficient for the biosynthesis of cortalcerone from glucose in vivo. The D-arabino-hexos-2-ulose-utilizing enzyme dehydrates certain aldosuloses and has been named aldos-2-ulose dehydratase. The enzyme, which appears to be a dimer of 95-kDa subunits, has been purified 450-fold. Additional properties of aldos-2-ulose dehydratase are described, including its apparent ability to catalyze two different steps in the proposed biosynthetic pathway for cortalcerone.
