    超长链酰基辅酶A合成酶(VLCS)将含22个或更多碳原子的超长链脂肪酸(VLCFA)激活为其CoA衍生物。我们克隆了编码大鼠肝酶(rVLCS)的基因的人类直系同源物(hVLCS)。hVLCS和rVLCS均包含620个氨基酸,主要在肝脏和肾脏中表达,并在其羧基末端具有潜在的过氧化物酶体靶向信号1(-LKL)。当在COS-1细胞中表达时,hVLCS激活了VLCFA木质酸(C24:0),长链脂肪酸(C16:0)和两个支链脂肪酸,植烷酸和豆酸。免疫荧光和免疫印迹研究将hVLCS定位于过氧化物酶体和内质网。在HepG2细胞的过氧化物酶体中,hVLCS面向基质而不是细胞质,在地形上定向。这个方向

    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/或共轭脂肪酸解为甘酸。我们在这里显示重组hBACAT也可以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

    Fatty acid transport proteins (FATP) function in fatty acid trafficking pathways, several of which have been shown to participate in the transport of exogenous fatty acids into the cell. Members of this protein family also function as acyl CoA synthetases with specificity towards very long chain fatty acids or bile acids. These proteins have two identifying sequence motifs: The ATP/AMP motif, an approximately
    脂肪酸转运蛋白 (FATP) 在脂肪酸转运途径中起作用,其中一些已被证明参与外源性脂肪酸转运到细胞中。该蛋白质家族的成员也作为酰基 CoA 合成酶发挥作用,对极长链脂肪酸胆汁酸具有特异性。这些蛋白质有两个识别序列基序:ATP/AMP 基序,大约 100 个氨基酸片段是 ATP 结合所需的,是形成腺苷酸的蛋白质超家族成员所共有的,以及由大约 50 个氨基酸组成的 FATP/VLACS 基序。酸残基,仅限于 FATP 家族的成员。后一种基序与酵母 FATP 直向同源物 FAt1p 中的脂肪酸转运有关。在目前使用含有 FAT1(编码 FAt1p)和 FAA1(编码主要酰基辅酶 A 合成酶 (Acsl) FAa1p)缺失的酵母菌株作为实验平台的研究中,特定鼠类 FATP1-FATP4 和 FATP6-FATP4 的表型和功能特性对蛋白质嵌合体进行了评估,以定义这些蛋白质中进一步区分脂肪酸转运和激

The very long- and long-chain acyl-CoAs are mainly chain-shortened and then transported to mitochondria for further metabolism. We have now identified and characterized two peroxisomal acyl-CoA thioesterases, named PTE-Ia

    previously cloned two human genes encoding proteins homologous to rat peroxisomal VLCS; one (hVLCS) is the human ortholog to the rat VLCS gene and another (hVLCS-H1) encodes a related heart-specific protein. Here, we report the cloning of a third gene (hVLCS-H2) and characterization of its protein product. The hVLCS-H2 gene is located on human chromosome 19 and encodes a 690-amino-acid protein. The amino

  • Dissecting the Role of Critical Residues and Substrate Preference of a Fatty Acyl-CoA Synthetase (FadD13) of Mycobacterium tuberculosis
    作者:Garima Khare、Vibha Gupta、Rakesh K. Gupta、Radhika Gupta、Rajiv Bhat、Anil K. Tyagi

    Newly emerging multi-drug resistant strains of Mycobacterium tuberculosis (M.tb) severely limit the treatment options for tuberculosis (TB); hence, new antitubercular drugs are urgently needed. The mymA operon is essential for the virulence and intracellular survival of M.tb and thus represents an attractive target for the development of new antitubercular drugs. This study is focused on the structure-function relationship of Fatty Acyl-CoA Synthetase (FadD13, Rv3089) belonging to the mymA operon. Eight site-directed mutants of FadD13 were designed, constructed and analyzed for the structural-functional integrity of the enzyme. The study revealed that mutation of Lys487 resulted in ∼95% loss of the activity thus demonstrating its crucial requirement for the enzymatic activity. Comparison of the kinetic parameters showed the residues Lys172 and Ala302 to be involved in the binding of ATP and Ser404 in the binding of CoenzymeA. The influence of mutations of the residues Val209 and Trp377 emphasized their importance in maintaining the structural integrity of FadD13. Besides, we show a synergistic influence of fatty acid and ATP binding on the conformation and rigidity of FadD13. FadD13 represents the first Fatty Acyl-CoA Synthetase to display biphasic kinetics for fatty acids. FadD13 exhibits a distinct preference for C26/C24 fatty acids, which in the light of earlier reported observations further substantiates the role of the mymA operon in remodeling the cell envelope of intracellular M.tb under acidic conditions. A three-dimensional model of FadD13 was generated; the docking of ATP to the active site verified its interaction with Lys172, Ala302 and Lys487 and corresponded well with the results of the mutational studies. Our study provides a significant understanding of the FadD13 protein including the identification of residues important for its activity as well as in the maintenance of structural integrity. We believe that the findings of this study will provide valuable inputs in the development of inhibitors against the mymA operon, an important target for the development of antitubercular drugs.
