  核苷酸与无机环三磷酸的磷酸化

  摘要：

  在各种条件下（P3m 与核苷酸的混合比、pH 值）在水溶液中研究了核苷酸（核苷 3'-和 5'-单磷酸酯，以及 2'-脱氧核苷 5'-单磷酸酯）与无机环三磷酸钠 (P3m) 的磷酸化、反应温度和时间）。(I) 未受保护的 5'-单磷酸核苷 (5'-NMP's) 很容易在顺式 2',3'-二醇处被 P3m 磷酸化，形成选择性核苷 2',5'-双（单磷酸）（2',5 '-NDP's）、核苷 3',5'-双（单磷酸）（3',5'-NDP）和核苷 2',3'-环状 5'-双（单磷酸）（cNDP）。(2) 5'-NMP's 的磷酸化强烈依赖于混合比、pH、反应温度和时间。在 P3m 与 5'-NMP's 的高混合比 (5:1–10:1)、高 pH (12) 和室温条件下，92-98% 的 5'-NMP's 转化为 3',5' -NDP 和 2'，大致等摩尔量的 5'-NDP。(3) 在 5'-NMP's

  Not only in bacteria but also in plant cells, guanosine-3',5'-tetraphosphate (ppGpp) is an important signaling molecule, that affects various cellular processes. In this study, we identified nucleoside diphosphates linked to some moiety X (Nudix) hydrolases, AtNUDX11, 15, 25, and 26, having ppGpp pyrophosphohydrolase activity from Arabidopsis plants. Among these, AtNUDX26 localized in chloroplasts had the highest V-max and k(cat) values, leading to high catalytic efficiency, k(cat)/K-m. The activity of AtNUDX26 required Mg2+ or Mn2+ ions as cofactor and was optimal at pH 9.0 and 50 degrees C. The expression of AtNUDX26 and of ppGpp metabolism-associated genes was regulated by various types of stress, suggesting that AtNUDX26 regulates cellular ppGpp levels in response to stress and impacts gene expression in chloroplasts. This is the first report on the molecular properties of ppGpp pyrophosphohydrolases in plants.

  The present invention relates generally to the field of screening or diagnostic applications in which a target is required to be displayed for binding to another molecule, or interaction or reaction with another molecule. In particular, the present invention relates to the use of DNA/protein interactions to immobilize or present one or more biomolecules for screening purposes. The present invention more particularly relates to double-stranded oligonucleotides, wherein said oligonucleotide comprises a first strand and a second strand, wherein: (a) said first strand comprises the sequence: 5′-N C R N D G T T G T A A C N D A-3′ (SEQ ID NO: 1) or an analogue or derivative of said sequence; and (b) said second strand comprises the sequence: 5′-T N D G T T A C A A C N D T N C -3′ (SEQ ID NO: 2) or an analogue or derivative of said sequence wherein R is a purine, N C and N D are each a DNA or RNA residue or analogue thereof, N D residues in said first strand and said second strand are sufficiently complementary to permit said N D residues to be annealed in the double-stranded oligonucleotide, and the sequence 5′-GTTGTAAC-3′ (SEQ ID NO: 3) of said first strand is annealed to the complementary sequence 5′GTTACAAC-3′ (SEQ ID NO: 4) of said second strand.
