    Uridine phosphorylase (UP) is a key enzyme in the pyrimidine salvage pathway, catalyzing the reversible phosphorolysis of uridine to uracil and ribose-1-phosphate (R1P). The human UP type 1 (hUP1) is a molecular target for the design of inhibitors intended to boost endogenous uridine levels to rescue normal tissues from the toxicity of fluoropyrimidine nucleoside chemotherapeutic agents, such as capecitabine
    尿苷磷酸化酶(UP)是嘧啶挽救途径中的关键酶,催化尿苷可逆磷酸化为尿嘧啶和核糖-1-磷酸(R1P)。人UP 1型(hUP1)是旨在设计抑制剂的分子靶标,这些抑制剂旨在提高内源性尿苷水平,以使正常组织免受氟嘧啶核苷化学治疗剂(如卡培他滨和5-氟尿嘧啶)的毒性作用。在这里,我们描述了一种获得均质重组hUP1的方法,并提出了初始速度,产物抑制和平衡结合数据。这些结果表明,hUP1通过稳态有序的bi bi动力学机制催化尿苷磷酸化,其中无机磷酸盐首先结合,然后与尿苷结合,尿嘧啶首先解离,然后R1P释放。平衡时的荧光滴定显示P(i)或R1P与hUP1的协同结合。基于pH-速率曲线提出了参与催化或底物结合的氨基酸残基。

The two forms of bound phosphate in the PNP.PO4 complex are interpreted to be phosphate positioned as the product in the nucleoside synthesis direction and as the reactant in the phosphorolysis reaction; their

  • Nontargeted in vitro metabolomics for high-throughput identification of novel enzymes in Escherichia coli
    作者:Daniel C Sévin、Tobias Fuhrer、Nicola Zamboni、Uwe Sauer
    DOI:10.1038/nmeth.4103
    日期:2017.2
    A method to screen proteins for enzymatic activity by incubating purified or overexpressed proteins with a metabolite extract and measuring changes in metabolite abundance using mass spectrometry enables high-throughput characterization of functionally uncharacterized proteins in Escherichia coli. Our understanding of metabolism is limited by a lack of knowledge about the functions of many enzymes. Here, we develop a high-throughput mass spectrometry approach to comprehensively profile proteins for in vitro enzymatic activity. Overexpressed or purified proteins are incubated in a supplemented metabolome extract containing hundreds of biologically relevant candidate substrates, and accumulating and depleting metabolites are determined by nontargeted mass spectrometry. By combining chemometrics and database approaches, we established an automated pipeline for unbiased annotation of the functions of novel enzymes. In screening all 1,275 functionally uncharacterized Escherichia coli proteins, we discovered 241 potential novel enzymes, 12 of which we experimentally validated. Our high-throughput in vitro metabolomics method is generally applicable to any purified protein or crude cell lysate of its overexpression host and enables performing up to 1,200 nontargeted enzyme assays per working day.

  • Conservation of structure and activity in Plasmodium purine nucleoside phosphorylases
    作者:Apirat Chaikuad、R Leo Brady
    DOI:10.1186/1472-6807-9-42

    Purine nucleoside phosphorylase (PNP) is central to purine salvage mechanisms in Plasmodium parasites, the causative agents of malaria. Most human malaria results from infection either by Plasmodium falciparum (Pf), the deadliest form of the parasite, or by the widespread Plasmodium vivax (Pv). Whereas the PNP enzyme from Pf has previously been studied in detail, despite the prevalence of Pv little is known about many of the key metabolic enzymes from this parasite, including Pv PNP. The crystal structure of Pv PNP is described and is seen to have many features in common with the previously reported structure of Pf PNP. In particular, the composition and conformations of the active site regions are virtually identical. The crystal structure of a complex of Pf PNP co-crystallised with inosine and arsenate is also described, and is found to contain a mixture of products and reactants – hypoxanthine, ribose and arsenate. The ribose C1' in this hybrid complex lies close to the expected point of symmetry along the PNP reaction coordinate, consistent with a conformation between the transition and product states. These two Plasmodium PNP structures confirm the similarity of structure and mechanism of these enzymes, which are also confirmed in enzyme kinetic assays using an array of substrates. These reveal an unusual form of substrate activation by 2'-deoxyinosine of Pv PNP, but not Pf PNP. The close similarity of the Pf and Pv PNP structures allows characteristic features to be identified that differentiate the Apicomplexa PNPs from the human host enzyme. This similarity also suggests there should be a high level of cross-reactivity for compounds designed to inhibit either of these molecular targets. However, despite these similarities, there are also small differences in the activities of the two Plasmodium enzymes.
    嘌呤核苷磷酸酶(PNP)是疟原虫寄生虫嘌呤回收机制的核心。大多数人类疟疾是由恶性疟原虫(Pf)或广泛传播的间日疟原虫(Pv)感染引起的。尽管之前已经对恶性疟原虫的PNP酶进行了详细研究,但人们对间日疟原虫的许多关键代谢酶知之甚少,包括间日疟原虫PNP。间日疟原虫PNP的晶体结构描述表明,它与之前报道的恶性疟原虫PNP结构有许多共同点。特别是,活性位点的组成和构象几乎完全相同。恶性疟原虫PNP与肌苷和砷酸盐共结晶的复合物的晶体结构也进行了描述,发现它包含产物和反应物(次黄嘌呤、核糖和砷酸盐)的混合物。这种混合复合物中的核糖C1'靠近PNP反应坐标轴上的预期对称点,与过渡态和产物态之间的构象一致。这两种疟原虫PNP的结构证实了这些酶的结构和机制的相似性,这也通过一系列底物的酶动力学测定得到了证实。这些结果表明,间日疟原虫PNP的2'-脱氧肌
