  Reversal of the Substrate Specificity of CMP N-Glycosidase to dCMP

  摘要：

  MilB is a CMP hydrolase involved in the early steps of biosynthesis of the antifungal compound mildiomycin. An enzyme from the bacimethrin biosynthetic pathway, BcmB, is closely related to MilB in both sequence and function. These two enzymes belong to the nucleoside 2'-deoxyribosyltransferase (NDT) superfamily. NDTs catalyze N-glycosidic bond cleavage of 2'-deoxynucleosides via a covalent 2-deoxyribosyl-enzyme intermediate. Conservation of key active site residues suggests that members of the NDT superfamily share a common mechanism; however, the enzymes differ in their substrate preferences. Substrates vary in the type of nucleobase, the presence or absence of a 2'-hydroxyl group, and the presence or absence of a 5'-phosphate group. We have determined the structures of MilB and BcmB and compared them to previously determined structures of NDT superfamily members. The comparisons reveal how these enzymes differentiate between ribosyl and deoxyribosyl nucleotides or nucleosides and among different nucleobases. The 1.6 angstrom structure of the MilB-CMP complex reveals an active site feature that is not obvious from comparisons of sequence alone. MilB and BcmB that prefer substrates containing 2'-ribosyl groups have a phenylalanine positioned in the active site, whereas NDT family members with a preference for 2'-deoxyribosyl groups have a tyrosine residue. Further studies show that the phenylalanine is critical for the specificity of MilB and BcmB toward CMP, and mutation of this phenylalanine residue to tyrosine results in a 1000-fold reversal of substrate specificity from CMP to dCMP.

  核苷磷酸化的新方法

  摘要：

  开发了一种新的磷酸化试剂2- O-（4,4'-二甲氧基三苯甲基）乙基磺酰lethan-2'-基磷酸酯（1），用于磷酸化核苷的伯醇和仲醇。在许多研究的实例中，磷酸化步骤的收率非常好（约80％至95％）。该方法不仅在核苷和核苷酸化学中，而且在诸如碳水化合物和氨基酸的生物分子的磷酸化中都有广泛的应用潜力。
