  Oxidations of N-(3-Indoleethyl) Cyclic Aliphatic Amines by Horseradish Peroxidase:  The Indole Ring Binds to the Enzyme and Mediates Electron-Transfer Amine Oxidation

  摘要：

  Although oxidations of aromatic amines by horseradish peroxidase (HRP) are well-known, typical aliphatic amines are not substrates of HRP. In this study, the reactions of N-benzyl and N-methyl cyclic amines with HRP were found to be slow, but reactions of N-(3-indoleethyl) cyclic amines were 2-3 orders of magnitude faster. Analyses of pH-rate profiles revealed a dominant contribution to reaction by the amine-free base forms, the only species found to bind to the enzyme. A metabolic study on a family of congeneric N-(3-indoleethyl) cyclic amines indicated competition between amine and indole oxidation pathways. Amine oxidation dominated for the seven- and eight-membered azacycles, where ring size supports the change in hybridization from sp(3) to sp(2) that occurs upon one-electron amine nitrogen oxidation, whereas only indole oxidation was observed for the six-membered ring congener. Optical difference spectroscopic binding data and computational docking simulations suggest that all the arylalkylamine substrates bind to the enzyme through their aromatic termini with similar binding modes and binding affinities. Kinetic saturation was observed for a particularly soluble substrate, consistent with an obligatory role of an enzyme-substrate complexation preceding electron transfer. The significant rate enhancements seen for the indoleethylamine substrates suggest the ability of the bound indole ring to mediate what amounts to medium long-range electron-transfer oxidation of the tertiary amine center by the HRP oxidants. This is the first systematic investigation to document aliphatic amine oxidation by HRP at rates consistent with normal metabolic turnover, and the demonstration that this is facilitated by an auxiliary electron-rich aromatic ring.

  色氨酸裂解酶 (NosL) 的机理研究：氰化物作为反应产物的鉴定

  摘要：

  色氨酸裂解酶 (NosL) 催化 3-甲基吲哚-2-羧酸和 3-甲基吲哚从 l-色氨酸形成。在本文中，我们提供了支持甲酸自由基中间体的证据，并证明氰化物是 NosL 催化与 l-色氨酸反应的副产物。这些实验需要对 NosL 机制进行重大修改，并揭示 NosL 和 HydG 之间的意外联系，HydG 是一种自由基 SAM 酶，在 [Fe-Fe] 氢化酶的金属簇生物合成过程中，由酪氨酸形成氰化物和一氧化碳。

  An easy three-step pathway for the synthesis of arylacet­aldehydes from the corresponding carboxylic acids in very high yields is described. Their use as precursors of 5-substituted-2-aminothiophenes is illustrated via a microwave-assisted Gewald reaction. This method allows obtaining the expected compounds in a shorter time and with better yields and purities than the classical procedures.
