    Transglutaminase-mediated transamidation of serotonin, dopamine and noradrenaline to fibronectin: Evidence for a general mechanism of monoaminylation
    摘要:
    The activity of some small GTPases is regulated by covalent transamidation of serotonin (5‐hydropxytryptamien) to glutamine residues of the enzymes. This process is mediated by transglutaminase (TGase) and is termed “serotonylation”. In addition, serotonylation of neural proteins and proteins of the extracellular matrix such as fibronectin has been demonstrated. Here we show that the catecholamines dopamine (DA) and noradrenaline (NA) inhibit serotonylation of fibronectin and that DA and NA themselves can be selectively transamidated into fibronectin by TGase. All three biogenic monoamines also block TGase‐mediated transamidation of another monoamine, monodansylacadaverine, into fibronectin, suggesting a general mechanism of TGase‐mediated “monoaminylation”.

  • Inactivation of dopamine .beta.-hydroxylase by .beta.-ethynyltyramine: kinetic characterization and covalent modification of an active site peptide

    stoichiometric, covalent modification of the enzyme. Analysis of the tryptic map following inactivation by [3H]-beta-ethynyltyramine reveals that the radiolabel is associated with a single, 25 amino acid peptide. The sequence of the modified peptide is shown to be Cys-Thr-Gln-Leu-Ala-Leu-Pro-Ala-Ser-Gly-Ile-His-Ile-Phe-Ala-Ser-Gln-Leu- His*- Thr-His-Leu-Thr-Gly-Arg, where His* corresponds to a covalently modified
    β-乙炔乙胺已被证明是一种有效的基于机制的多巴胺β-羟化酶(DBH)抑制剂。酶的伪一级反应,时间依赖性失活,失活对抗坏血酸和氧共底物的存在,酪胺(底物)和1-(3,5-二-4-羟基苄基)的能力证明了这一点。咪唑-2-酮(竞争性多底物抑制剂)可防止失活,并且β-乙炔基酪胺对酶具有高亲和力。β-乙炔基酪胺使DBH失活伴随着酶的化学计量,共价修饰。通过[3H]-β-乙炔基酪胺灭活后的胰蛋白酶图分析表明,放射性标记与单个25个氨基酸的肽相关。修饰肽的序列显示为Cys-Thr-Gln-Leu-Ala-Leu-Pro-Ala-Ser-Gly-Ile-His-Ile-Phe-Ala-Ser-Gln-Leu-His * -Thr -His-Leu-Thr-Gly-Arg,其中His *对应于共价修饰的组酸残基。在使用分离的β-乙炔基酪胺对映体的研究中,我们发现R对映体是可逆的竞争性抑制剂,相对于酪胺底物,Ki为7

    在这里,我们报告人苯乙醇胺N-甲基转移酶(PNMT)的三种晶体结构复合物,一种与结合了柔性乙醇胺侧链(p-章鱼胺)的底物结合,第二种与半刚性类似物底物[顺式((1R,2S) )-2-基-1-四醇,顺式((1R,2S)-AT],第三个带有反式(1S,2S)-2-基-1-四醇[反式((1S,2S)-AT]充当PNMT抑制剂而不是底物。对氯胺的柔性乙醇胺基团的关键β-羟基与酸性残基Asp267之间的介导相互作用可能在正确定位侧链以使胺发生甲基化方面起关键作用。与Glu219的第二次交互可能起的作用较小。催化作用可能是通过Glu185的作用使胺脱质子而发生的。该残基的突变显着降低了kcat,而不影响Km。顺式-(1R,2S)-AT的结合方式支持以下观点,即该底物是柔性PNMT底物的构象受限类似物,因为它与酶形成的相互作用类似于对位章鱼胺所观察到的。相反,与顺式(1R,2S)-AT相比,抑制剂

    Noradreanline and adrenaline were substrates for both forms of the enzyme in all regions studied. The total MAO activity was found to be highest in the hypothalamus and lowest in the cerebellar cortex. Use of the selective MAO inhibitors clorgyline and (?)-deprenyl also showed adrenaline and noradrenaline to be substrates for both forms of the enzyme in rat brain. In human cerebral cortex and rat brain the two
