    Insights into lignin primary structure and deconstruction from Arabidopsis thaliana COMT (caffeic acid O-methyl transferase) mutant Atomt1
    摘要:
    拟南芥突变体 Atomt1 木质素与野生型植物中的原生木质素不同,纤维细胞壁中由 sinapyl (S) 醇衍生的亚结构被 5-hydroxyconiferyl 醇 (5OHG) 衍生的分子取代。在木质素的程序化组装过程中,由于 8-O-4′ 自由基-自由基偶联后瞬时形成的醌基甲烷的分子内环化作用,这些醌基甲烷会形成苯并二恶烷亚结构。与野生型相比,Atomt1 突变体中 8-O-4′ 单元间连接的硫代酸裂解表明,可裂解的桧醇(S)和松柏醇(G)衍生的单体分子以约 2 :1 的比例减少。此外,木质素降解分析还导致 Atomt1 突变体释放出 5OHG-5OHG-G 三聚体,然后进一步裂解。值得注意的是,释放出的三聚体提供了对木质素一级结构的新认识:在聚合物组装过程中,第一个 5OHG 分子通过 C8-O-X 单元间连接,而随后单体的添加显然涉及 5OHG 和 G 分子以 2 :1 的总比例。因此,这些定量数据让我们进一步了解了在这两种情况下,原生木质素中的单元间连接频率是如何在组装过程中保持不变(或接近不变)的,同时也为解决木质素大分子组装的整体问题提供了更多动力,即单体添加类型和主序是如何受控的。

  • [EN] PREPARATION PROCESS OF ORTHO ALKOXY BISPHENOL MONOMERS<br/>[FR] PROCÉDÉ DE PRÉPARATION DE MONOMÈRES D'ORTHOALCOXY BISPHÉNOL
    申请人:UNIV LEUVEN KATH
    公开号:WO2019002503A1
    公开(公告)日:2019-01-03
    A process for making ortho alkoxy bisphenol monomers includes contacting an (alk-1-enyl)alkoxyphenol (type 1) with an alkoxyphenol (type 2) in the presence of an acidic catalyst. Both type of renewable phenols (type 1 and 2) can be generated from lignocellulosic biomass. The use of such alkoxy phenols as a precursor to bisphenol monomers has the potential to reduce the cost and environmental impact of structural materials, while meeting or exceeding the performance of current petroleum-derived polymers, such as thermoplastics and thermoset resins.
    制备邻烷氧基双酚单体的过程包括将(烯基)烷氧基酚(类型1)与烷氧基酚(类型2)在酸性催化剂存在下接触。这两种可再生酚(类型1和2)均可从木质纤维素生物质中生成。将这种烷氧基酚用作双酚单体的前体有潜力降低结构材料的成本和环境影响,同时满足或超越当前石油衍生聚合物(如热塑性塑料和热固性树脂)的性能。

    The present invention relates to a probe compound that can comprise any substrate or metabolite of an enzymatic reaction in addition to an indicator component, such as, for example, a fluorescence dye, or the like. Moreover, the present invention relates to means for detecting enzymes in form of an array, which comprises any number of probe compounds of the invention which each comprise a different metabolite of interconnected metabolites representing the central pathways in all forms of life. Moreover, the present invention relates to a method for detecting enzymes involving the application of cell extracts or the like to the array of the invention which leads to reproducible enzymatic reactions with the substrates. These specific enzymatic reactions trigger the indicator (e.g. a fluorescence signal) and bind the enzymes to the respective cognate substrates. Moreover, the invention relates to means for isolating enzymes in form of nanoparticles coated with the probe compound of the invention. The immobilisation of the cognate substrates or metabolites on the surface of nanoparticles by means of the probe compounds allows capturing and isolating the respective enzyme, e.g. for subsequent sequencing.
