Pyrimidine nucleoside monophosphate kinase (EC 2.7.4.14) catalyzes the phosphorylation of various pyrimidine nucleoside monophosphates to their corresponding diphosphates. In addition to its role in the synthesis of nucleic acid precursors, this enzyme is essential for the conversion of the antileukemic agent 1-/3-o-arabinofuranosylcytosine to its active metabolite 1-/3-o-arabinofuranosyl 5 -tr...
Changes in nucleotide pools and extracellular nucleotides during the developmental cycle of the myxobacterium Myxococcus xanthus were determined using a high-pressure liquid chromatography nucleotide analyzer. A general increase in all nucleotide pools occurred during the morphological phase of glycerol conversion of vegetative cells to myxospores. The levels of the nucleoside triphosphate pool...
The units of RNA, termed ribonucleoside monophosphates (rNMPs), have been recently found as the most abundant defects present in DNA. Despite the relevance, it is largely unknown if and how rNMPs embedded in DNA can change the DNA structure and mechanical properties. Here, we report that rNMPs incorporated in DNA can change the elastic properties of DNA. Atomic force microscopy (AFM)-based sing...
The relatively large amounts of pseudouridine in that fraction of the ribonucleic acid concerned with the transfer of activated amino acids to ribosomes for peptide bond formation (l-4) suggests that this unusual base may play an essential role in this reaction, and that a specific mechanism exists for its incorporation into interribonucleotide linkage. To obtain information on the nature of th...
