    硫酸化的苯基2-乙酰氨基-2-脱氧-D-吡喃半乳糖苷的合成。4-O-硫酸化的苯基2-乙酰氨基-2-脱氧-β-D-吡喃半乳糖苷是一种竞争性受体,它可以减少N-乙酰半乳糖胺4-硫酸盐6-O-磺基转移酶对硫酸软骨素的硫酸化。
    摘要:
    我们之前已经克隆了N-乙酰半乳糖胺4-硫酸盐6-O-磺基转移酶(GalNAc4S-6ST),它将硫酸盐从3'-磷酸腺苷5'-磷酸硫酸盐(PAPS)转移到GalNAc 4-硫酸盐残基的C-6羟基上。硫酸软骨素A形成含有GlcA-GalNAc(4,6-SO(4))重复单元的硫酸软骨素E。为了研究硫酸软骨素E的功能,开发GalNAc4S-6ST特异性抑制剂非常重要。因为GalNAc4S-6ST需要连接到GalNAc残基的C-4羟基上的硫酸基团作为受体,所以硫酸化的GalNAc残基有望与GalNAc4S-6ST相互作用并影响其活性。在这项研究中,我们合成了在C-3,C-4,或C-6羟基,并检查了它们对重组GalNAc4S-6ST的抑制活性。我们发现,苯基β-GalNAc(4SO(4))竞争性抑制GalNAc4S-6ST,并且还可以作为受体。衍生自苯基β-GalNAc(4SO(4))的硫酸化产物与苯基β-GalNAc(4

  • Mechanism of Human Nucleocytoplasmic Hexosaminidase D

    Mammalian β-hexosaminidases have been shown to play essential roles in cellular physiology and health. These enzymes are responsible for the cleavage of the monosaccharides N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) from cellular substrates. One of these β-hexosaminidases, hexosaminidase D (HexD), encoded by the HEXDC gene, has received little attention. No mechanistic studies have focused on the role of this unusual nucleocytoplasmically localized β-hexosaminidase, and its cellular function remains unknown. Using a series of kinetic and mechanistic investigations into HexD, we define the precise catalytic mechanism of this enzyme and establish the identities of key enzymic residues. The preparation of synthetic aryl N-acetylgalactosaminide substrates for HexD in combination with measurements of kinetic parameters for wild-type and mutant enzymes, linear free energy analyses of the enzyme-catalyzed hydrolysis of these substrates, evaluation of the reaction by nuclear magnetic resonance, and inhibition studies collectively reveal the detailed mechanism of action employed by HexD. HexD is a retaining glycosidase that operates using a substrate-assisted catalytic mechanism, has a preference for galactosaminide over glucosaminide substrates, and shows a pH optimum in its second-order rate constant at pH 6.5–7.0. The catalytically important residues are Asp148 and Glu149, with Glu149 serving as the general acid/base residue and Asp148 as the polarizing residue. HexD is inhibited by Gal-NAG-thiazoline (Ki = 420 nM). The fundamental insights gained from this study will aid in the development of potent and selective probes for HexD, which will serve as useful tools to improve our understanding of the physiological role played by this unusual enzyme.
    哺乳动物的β-己糖胺酶在细胞生理和健康中扮演着重要角色。这些酶负责从细胞底物中断裂单糖N-乙酰葡萄糖胺(GlcNAc)和N-乙酰半乳糖胺(GalNAc)。其中一种β-己糖胺酶,即己糖胺酶D(HexD),由HEXDC基因编码,一直以来受到的关注较少。目前没有机制研究专注于这种在细胞核和细胞质中定位的非典型β-己糖胺酶的作用,其细胞功能仍然未知。通过一系列对HexD的动力学和机制研究,我们确定了这种酶的确切催化机制,并确定了关键酶残基的身份。结合对野生型和突变型酶的动力学参数测定,对酶催化水解这些底物的线性自由能分析,通过核磁共振评估反应,以及抑制研究,共同揭示了HexD所采用的详细作用机制。HexD是一种保留型糖苷酶,采用底物辅助的催化机制,偏好半乳糖胺而非葡萄糖胺底物,并在pH 6.5-7.0的第二级速率常数中显示出最适pH。在催化中重要的残基是Asp148和Glu149,其中Glu149作为广义酸/碱残基,Asp148作为极化残基。HexD被Gal-NAG-噻唑烷抑制(Ki = 420 nM)。通过这项研究所获得的基本洞见将有助于开发强效且选择性的HexD探针,这将作为有用的工具来增进我们对这种非典型酶在生理学中作用的了解。
