    15N 固态 NMR 提供氧化黄素反应位点的灵敏探针
    摘要:
    黄素对于多种酶和电子传递蛋白的反应至关重要。人们对了解黄素在不同蛋白质背景下表现出的不同反应性的基础非常感兴趣。我们提出固态核磁共振(SS-NMR)作为直接观察黄素环反应位置的工具,从而获得其前沿轨道的信息。我们现在报告氧化还原活性氮 N1 和 N5 以及 N3 的 SS-NMR 信号。根据理论预测和我们的计算,N5 的化学位移张量超过 720 ppm 宽。N3 的信号可以根据 N1 和 N5 不存在的 1H 耦合以及仅 170 ppm 的位移张量跨度来区分,这与 N3 较低的芳香性和缺乏非键合孤对电子一致。N5 和 N1 的各向同性位移和跨度反映了“吡啶型”N 的化学位移范围的两个相反的极端,分别与其亲电和亲核化学反应性一致。黄素还原后,N5 的化学位移张量急剧收缩到小于 110 ppm 的跨度,并且各向同性化学位移变化约 300 ppm。两者都与 N5 非键合孤对电子的损失和芳香性降低一致,并说明了

    Redox reaction between m-thiocresol and riboflavin glycosides with 2:1 complex formation; regulation by the steric effect of sugar in the side chain
    摘要:
    We investigated the reduction of riboflavin-2', 3', 4', 5'-tetra-acetate (AcB2), riboflavin-1'-glucoside-2'', 3'', 4'', 6'', 2', 3', 4', 5'-hepta-acetate (AcB2gl) and lumiflavin using m-thiocresol (mTc) in the presence of tetrabutylammonium hydroxide. The series of rate constants for AcB2 and AcB2gl reductions indicated that modified Lineweaver-Burk plots were best fit by assuming a 1:2 complex formation. The complex formation in the reaction was supported by the 2-D nuclear Overhauser enhancement spectroscopy and circular dichroism spectra. The modified Michaelis-Menten constants (Km) for AcB2 and AcB2gl with mTc were 1.32 and 0.86x10-3M2, respectively, and the maximum rate constant k2 were 4.45 and 4.35x10-2M-1s-1, respectively. The E1/2 values of AcB2 and AcB2gl were-331 and-341mV, respectively, which indicated that their reduction activities were almost the same. It was established that the redox function depended on the formation of the complex and was regulated by the steric effect of the sugar in the side chain.

  • Model Systems for Flavoenzyme Activity. Control of Flavin Recognition via Specific Electrostatic Interactions
    作者:Allan J. Goodman、Eric C. Breinlinger、Catherine M. McIntosh、Lisa N. Grimaldi、Vincent M. Rotello

    [structure: see text] A model system has been used to study the interactions of dipole-containing aromatic systems with oxidized and reduced flavin. Ab initio computational and experimental studies show that dipole orientation within the host is a critical determinant for recognition and redox behavior of the flavin guest.

The reduction product yield was proportional to the yield of the N(5) flavin-epoxide adduct intermediate, and the rate of the reaction was proportional to the dihydroflavin concentration. These observations are consistent with these reduction products resulting from bimolecular reaction between the
