    A series of primary and secondary carboxyalkylcobalamins with (CH2)nCOOH groups (n = 1 - 3), CH2-CH(CH3)COOH, CH(R)COOH (R = CH3, C2H5, n-C3H7), CH(CH3)(CH2)nCOOH (n = 1, 2) and CH(COOH)CH2COOH attached to cobalt were synthesized or generated in situ, mostly by the reaction of vitamin B12s or hydridocobalamin with the respective α- or ω-substituted halocarboxylic acids and reactions with olefinic carboxylic

    Glutathionylcobalamin, nitrocobalamin and sulfitocobalamin are important cobalamin metabolites isolable from human tissues. Herein we demonstrate that a procedure used to synthesize and isolate γ-glutamylcysteinylcobalamin and glutathionylcobalamin in aqueous solution in high yield and purity can be used to synthesize other novel, biologically relevant thiolatocobalamins, including D,L-homocysteinylcobalamin, N-acetyl-L-cysteinylcobalamin (Na+ salt) and 2-N-acetylamino-2-carbomethoxy-L-ethanethiolatocobalamin, as well as other non-alkylcobalamins, such as sulfitocobalamin (Na+ salt) and nitrocobalamin. This uncomplicated, general procedure will assist researchers in identifying unknown cobalamin metabolites isolated from biological samples, and researchers interested in studying the uptake and intracellular cobalamin processing mechanisms utilizing non-alkylcobalamin derivatives that are not yet commercially available. The X-ray structure and XAS spectrum of N-acetyl-L-cysteinylcobalamin are also presented.

    The equilibria and kinetics of substitution of the 5,6-dimethylbenzimidazole at the alpha site of beta-(N-methylimidazolyl)cobalamin by N-methylimidazole have been investigated, and the product, bis(N-methylimidazolyl)cobalamin, has been characterized by visible and 1H NMR spectroscopies. The equilibrium constant for (N-MeIm)Cbl+ + N-MeIm right harpoon over left harpoon (N-MeIm)2Cbl+ was determined

    EutT from Salmonella enterica is a member of a class of enzymes termed ATP:Co(I)rrinoid adenosyltransferases (ACATs), implicated in the biosynthesis of adenosylcobalamin (AdoCbl). In the presence of cosubstrate ATP, ACATs raise the Co(II)/Co(I) reduction potential of their cob(II)alamin [Co(II)Cbl] substrate by >250 mV via the formation of a unique four-coordinate (4c) Co(II)Cbl species, thereby facilitating
    来自沙门氏菌的 EutT 是一类被称为 ATP:Co(I)rrinoid 腺苷转移酶 (ACAT) 的酶的成员,与腺苷钴胺素 (AdoCbl) 的生物合成有关。在共底物 ATP 存在的情况下,ACAT 通过形成独特的四配位,将其 cob(II)alamine [Co(II)Cbl] 底物的 Co(II)/Co(I) 还原电位提高 >250 mV。 4c) Co(II)Cbl 物质,从而促进形成 AdoCbl 产物所需的“超亲核”cob(I) 胺中间体。先前对 EutT 的动力学研究揭示了 HX11CCX2C(83) 基序对催化活性的重要性,并提出了该基序中的残基作为二价过渡金属辅因子 [例如 Fe(II) 或 Zn( II)]。这个主题在其他 ACAT 家族中是不存在的,表明 EutT 采用独特的 AdoCbl 形成机制。为了评估与 HX11CCX2C(83) 基序结合的金属离子如何影响 EutT

Key features of the structure of gamma-glutamylcysteinylcobalamin include (i) a normal Co-S bond length of 2.267(2) A, (ii) a Co-N(axial) bond length of 2.049(6) A, (iii)
    谷胱甘肽钴胺素(γ-谷氨酰基半胱氨酸甘氨酰钴胺素;γ-GluCysGly-Cbl)是一种天然产物,在活性B(12)辅酶腺苷钴胺素和甲基钴胺素的生物合成中起中间体的作用。本研究感兴趣的是谷胱甘肽钴胺素与其他硫代latocobalamins相比的独特稳定性,特别是半胱氨酰钴胺素Cys-Cbl的>或= 6 x 10(4)倍。为了确定谷胱甘肽三肽的哪些部分有助于谷胱甘肽钴胺素的整体稳定性,使用了两个半胱氨酸二肽,它们是谷胱甘肽的截短形式,来合成其相应的钴胺素,特别是γ-谷氨酰半胱氨酸Cbl(γ-GluCys-Cbl)和半胱氨酰甘氨酰钴胺素(CysGly-Cbl)。与谷胱甘肽Cbl一样,二肽γ-GluCys-Cbl形成稳定的硫代latobabalamin。然而,最有趣的是,观察到CysGly-Cbl像Cys-Cbl一样不稳定。结果要求与半胱氨酰钴胺素及其类似物相比,谷胱甘肽钴胺素及其同类物的额外稳定
