  Dual activity of certain HIT-proteins:A. thalianaHint4 andC. elegansDcpS act on adenosine 5′-phosphosulfate as hydrolases (forming AMP) and as phosphorylases (forming ADP)

  摘要：

  Histidine triad (HIT)‐family proteins interact with different mono‐ and dinucleotides and catalyze their hydrolysis. During a study of the substrate specificity of seven HIT‐family proteins, we have shown that each can act as a sulfohydrolase, catalyzing the liberation of AMP from adenosine 5′‐phosphosulfate (APS or SO4‐pA). However, in the presence of orthophosphate, Arabidopsis thaliana Hint4 and Caenorhabditis elegans DcpS also behaved as APS phosphorylases, forming ADP. Low pH promoted the phosphorolytic and high pH the hydrolytic activities. These proteins, and in particular Hint4, also catalyzed hydrolysis or phosphorolysis of some other adenylyl‐derivatives but at lower rates than those for APS cleavage. A mechanism for these activities is proposed and the possible role of some HIT‐proteins in APS metabolism is discussed.

  Characterisation of stress protein LysU. Enzymic synthesis of diadenosine 5′,5‴-P¹,P⁴-tetraphosphate (Ap₄A) analogues by LysU

  摘要：

  The stress protein LysU (lysyl tRNA synthetase) has been purified from a recombinant strain of Escherichia coli expressing the plasmid pXLys5, and kinetically characterised. Preparative syntheses of analogues of the biologically important molecule diadenosine 5',5'''-P-1,P-4-tetraphosphate (Ap(4)A) are then achieved in good yield by enzyme catalysis, using purified LysU.

  indicated by NMR. The conformation around the glycosidic angle in NpnN′s was found to be anti/high anti and the preferred conformation around the C4′–C5′, C5′–O5′ bonds was found to be gauche–gauche (gg). The ribose moiety in NpnN′s showed a small preference for the S conformation, but when attached to cytosine the ribose ring preferred the N conformation. However, no predominant conformation was observed

  二核苷多磷酸盐或二核苷酸（Np n N'； N，N'= A，U，G，C；n = 2-7）是天然存在的生理活性化合物。尽管对二核苷酸的兴趣以及它们的构象与其生物学功能的相关性，但是对二核苷酸的构象的研究还不够充分。因此，在这里，我们通过各种NMR技术对一系列Np n N'Na +盐（N = A，G，U，C； N'= A，G，U，C；n = 2–5）进行了构象分析。。如NMR所示，除Up 4/5 U外，所有研究的二核苷酸均在水溶液中形成分子内碱基堆积相互作用。Np n中糖苷角周围的构象发现N's是抗/高抗性，并且发现C4'-C5'，C5'-O5'键周围的优选构象是gauche – gauche（gg）。Np n N's中的核糖部分显示出对S构象的偏爱，但是当连接到胞嘧啶时，核糖环则优先选择N构象。然而，在任何二核苷酸中均未观察到核糖部分的主要构象。Ap 2 A和Ap 4 A Na +盐的分子动力学模拟支持了实验结果。此外，针对Ap

From pH 6 to 9 the hydrolysis is slow and pH-independent. Base-catalysed hydrolysis is observed in NaOH-solutions.

  已在较宽的pH范围内研究了腺苷5'，5'-三磷酸水解为AMP和ADP的过程。在酸性条件下，反应显示出对水合氢离子浓度的一级依赖性。pH低于3时，速率增加开始趋于平稳。从pH 6到9，水解缓慢且不依赖pH。在NaOH溶液中观察到碱催化的水解。在碱性条件下，还观察到分子内亲核性攻击产生磷酸盐的3'，5'-cAMP，但它比分子间反应慢。腺苷部分的去纯化在酸性和碱性条件下都与水解竞争，但是机理不同。在酸性条件下研究了Ap（3）A水解和腺苷部分的去纯化的温度依赖性，并计算了反应的活化参数。这项工作的结果反映了一个事实，即带负电荷的聚磷酸盐基团对亲核攻击非常有抵抗力。仅在酸性条件下才能观察到有效的催化作用，在该条件下磷酸基团会质子化。一般的酸或碱不催化水解。此外，仅在高碱浓度下观察到氢氧根离子催化的裂解，而其他带负电荷的亲核试剂未攻击多腺苷多磷酸的磷酸基团。一般的酸或碱不催化水解。此外，仅在高碱浓度下

  dinucleoside polyphosphates. Fhit catalyzes the Mg2+-dependent hydrolysis of P1-5'-O-adenosine-P3-5'-O-adenosine triphosphate (Ap3A) to AMP and MgADP. Mutation of His96 to glycine disables Fhit as a catalyst for the hydrolysis of phosphoanhydrides such as Ap3A. However, the mutated enzyme H96G-Fhit efficiently catalyzes the synthesis of phosphoanhydride bonds in reactions of nucleoside-5'-phosphimidazolides
