制备方法与用途

生物活性

Coenzyme FO 是一种脱氮黄素发色团,在产甲烷途径中起着重要的氢化物受体/供体作用。其形成由两种独立的半胱氨酸-腺苷-S-甲基转移酶(radical SAM)活性位点调节,分别位于 CofG 和 CofH 酶中或共同存在于 FbiC 酶中。这两个 radical SAM 域构成了 Fo 合成酶的功能域。

在极端嗜热甲烷球菌属(Methanocaldococcus jannaschii)中,Coenzyme F420 通过八种酶的作用被合成,并形成脱氮黄素色原(Fo),这是最后一个未解决的步骤。Coenzyme F420 是甲烷生成代谢中的中心低还原电位电子载体。它在氢气作用下由依赖 Coenzyme F420 的氢化酶还原。

在分枝杆菌中,Coenzyme F420 作为特定葡萄糖-6-磷酸脱氢酶(Fgd)的辅因子参与了水合转移反应。Coenzyme F420 在所有甲烷生成和某些非甲烷生成古菌中普遍存在,并参与能量代谢、NADP 还原、氧解毒以及硫代硫酸盐还原过程。通过将 NO2 转化为 NO 并利用 Coenzyme F420H2,结核分枝杆菌(M. tuberculosis)可以降低巨噬细胞抗菌作用的有效性。

  • A robust synthesis of 7,8-didemethyl-8-hydroxy-5-deazariboflavin
    作者:Matthias Bender、Henrik Mouritsen、Jens Christoffers
    DOI:10.3762/bjoc.12.89
    日期:——

    The biosynthetic precursor of redox cofactor F420, 7,8-didemethyl-8-hydroxy-5-deazariboflavin, was prepared in four steps from 6-chlorouracil, 2-chloro-4-hydroxybenzaldehyde and bis-isopropylidene protected D-ribose. The latter aldehyde was transformed to the corresponding protected ribitylamine via the oxime, which was submitted to reduction with LiAlH4. Key advantage compared to previous syntheses is the utilization of a polyol-protective group which allowed the chromatographic purification of a key-intermediate product providing the target compound with high purity.

  • Biosynthesis of F<sub>0</sub>, Precursor of the F<sub>420</sub> Cofactor, Requires a Unique Two Radical-SAM Domain Enzyme and Tyrosine as Substrate
    作者:Laure Decamps、Benjamin Philmus、Alhosna Benjdia、Robert White、Tadhg P. Begley、Olivier Berteau
    DOI:10.1021/ja307762b
    日期:2012.11.7
    Cofactors play key roles in metabolic pathways. Among them F-420 has proved to be a very attractive target for the selective inhibition of archaea and actinobacteria. Its biosynthesis, in a unique manner, involves a key enzyme, F-0-synthase. This enzyme is a large monomer in actinobacteria, while it is constituted of two subunits in archaea and cyanobacteria. We report here the purification of both types of F-0-synthase and their in vitro activities. Our study allows us to establish that F-0-synthase, from both types, uses 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione and tyrosine as substrates but not 4-hydroxylphenylpyruvate as previously suggested. Furthermore, our data support the fact that F-0-synthase generates two 5'-deoxyadenosyl radicals for catalysis which is unprecedented in reaction catalyzed by radical SAM enzymes.
  • Biosynthetic Versatility and Coordinated Action of 5′-Deoxyadenosyl Radicals in Deazaflavin Biosynthesis
    作者:Benjamin Philmus、Laure Decamps、Olivier Berteau、Tadhg P. Begley
    DOI:10.1021/ja513287k
    日期:2015.4.29
    Coenzyme F-420 is a redox cofactor found in methanogens and in various actinobacteria. Despite the major biological importance of this cofactor, the biosynthesis of its deazaflavin core (8-hydroxy-5-deazaflavin, F-o) is still poorly understood. F-o synthase, the enzyme involved, is an unusual multidomain radical SAM enzyme that uses two separate 5'-deoxyadenosyl radicals to catalyze F-o formation. In this paper, we report a detailed mechanistic study on this complex enzyme that led us to identify (1) the hydrogen atoms abstracted from the substrate by the two radical SAM domains, (2) the second tyrosine-derived product, (3) the reaction product of the CofH-catalyzed reaction, (4) the demonstration that this product is a substrate for CofG, and (5) a stereochemical study that is consistent with the formation of a p-hydroxybenzyl radical at the CofH active site. These results enable us to propose a mechanism for F-o synthase and uncover a new catalytic motif in radical SAM enzymology involving the use of two 5'-deoxyadenosyl radicals to mediate the formation of a complex heterocycle.
