    Assignment of Endogenous Substrates to Enzymes by Global Metabolite Profiling
    摘要:
    Enzymes regulate biological processes through the conversion of specific substrates to products. Therefore, of fundamental interest for every enzyme is the elucidation of its natural substrates. Here, we describe a general strategy for identifying endogenous substrates of enzymes by untargeted liquid chromatography-mass spectrometry (LC-MS) analysis of tissue metabolomes from wild-type and enzyme-inactivated organisms. We use this method to discover several brain lipids regulated by the mammalian enzyme fatty acid amide hydrolase (FAAH) in vivo, including known signaling molecules (e.g., the endogenous cannabinoid anandamide) and a novel family of nervous system-enriched natural products, the taurine-conjugated fatty acids. Remarkably, the relative hydrolytic activity that FAAH exhibited for lipid metabolites in vitro was not predictive of the identity of specific FAAH substrates in vivo. Thus, global metabolite profiling establishes unanticipated connections between the proteome and metabolome that enable assignment of an enzyme's unique biochemical functions in vivo.

    Bile acid-CoA:amino acid N-acyltransferase (BACAT) catalyzes the conjugation of bile acids to glycine and taurine for excretion into bile. By use of site-directed mutagenesis and sequence comparisons, we have identified Cys-235, Asp-328, and His-362 as constituting a catalytic triad in human BACAT (hBACAT) and identifying BACAT as a member of the type I acyl-CoA thioesterase gene family. We therefore
    胆汁酸-CoA:氨基酸N-酰基转移酶(BACAT)催化胆汁酸与甘氨酸和牛磺酸的结合,从而排泄到胆汁中。通过使用定点诱变和序列比较,我们已鉴定出Cys-235,Asp-328和His-362构成人BACAT(hBACAT)中的催化三联体,并将BACAT鉴定为I型酰基辅酶A硫酯酶基因家族。因此,我们假设hBACAT也可能将脂肪酰基辅酶A和/或共轭脂肪酸水解为甘氨酸。我们在这里显示重组hBACAT也可以水解长链和非常长链的饱和酰基CoAs(主要是C16:0-C26:0),并且通过质谱法验证了hBACAT还可以将脂肪酸缀合到甘氨酸上。组织表达研究表明,BACAT在肝,胆囊以及近端和远端肠中都有强表达。然而,BACAT还可以在与胆汁酸形成和运输无关的多种组织中表达,这表明在调节长链脂肪酸的细胞内水平方面也起着重要的作用。在人皮肤成纤维细胞中的绿色荧光蛋白定位实验表明,hBACAT酶主要是胞质的。因此

    acyl-AMP ligase (FadD26) for biosynthesis of phthiocerol dimycocerosates (PDIMs), which are nonglycosylated lipids structurally related to PGLs. To our knowledge, the partially overlapping PGL and PDIM biosynthetic pathways provide the first example of two distinct, pathway-dedicated acyl-AMP ligases loading the same type I polyketide synthase system with two alternate starter units to produce two structurally
    酚类糖脂(PGL)是致病性分枝杆菌特有的聚酮化合物合成酶衍生的糖脂。在几种临床相关物种中发现了PGL,包括各种结核分枝杆菌菌株,麻风分枝杆菌和几种非结核性分枝杆菌病原体,例如海洋分枝杆菌。多方面的调查表明PGL具有毒性,因此强调了对PGL生物合成的深入了解的相关性。我们报道了突变和生化研究,这些研究询问了由迭代聚酮化合物合酶Pks15 / 1合成的PGL生物合成中间体(对羟基苯基链烷酸酯)被转移至非迭代聚酮化合物合酶PpsA的M. marinum酰基链延伸的机理。我们的发现支持了一种模型,其中中间体的转移依赖于对羟基苯烷酰基-AMP连接酶(FadD29)作为迭代和非迭代合酶系统之间的中介。我们的研究结果还建立了PpsA的对羟基苯甲酸扩展能力,PpsA是多亚基非迭代聚酮化合物合酶系统的第一个作用酶。值得注意的是,该非迭代系统还通过特定的脂肪酰基-AMP连接酶(FadD26)装载了脂肪酸,用于

    仅在生长缓慢的致病性分枝杆菌的细胞壁中发现含有苯硫酚和苯酚硫酚的表面暴露的异常脂质,并且被认为在宿主与病原体的相互作用中起重要作用。邻苯二酚和苯酚间苯二酚的生物合成的酶学和分子遗传学是未知的。我们假设一组多功能酶和一组基因(pps)的结构域结构,这些基因将编码这些酶用于苯硫酚和苯酚硫酚的生物合成。通过用牛分枝杆菌酸合酶和脂肪酸合酶基因的假定同源结构域作为探针筛选牛分枝杆菌BCG的基因组文库,鉴定了包含假定的pps基因簇的粘粒。在结核分枝杆菌和麻风分枝杆菌的基因组文库中也鉴定出同源粘粒。通过引入潮霉素抗性基因作为正选择标记和sacB基因作为反选择标记,用由BCG粘粒制成的pps破坏构建体转化牛分枝杆菌BCG。通过聚合酶链反应和Southern杂交证实通过双重重组的同源重组破坏基因。色谱分析表明,该基因敲除突变体未产生苯酚硫代胆甾醇衍生物,霉菌苷B和苯硫酚二聚己二酸酯。该结果证实了pps基因的
