Example sentences for: dinucleoside

How can you use “dinucleoside” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Catalytic activity of the Fhit ApppA hydrolase depends on His96 [ 14 16 ] . To test whether the active site of Hnt2 is necessary to control dinucleoside polyphosphate accumulation in vivo , wild-type and mutant alleles of HNT2 that differ at His109, corresponding to human Fhit His96, were expressed from the HNT2 promoter on plasmids (Table 3) in hnt2ΔADE2 strain BY71-6c.

  • In the case of disruption of the Fhit and Hnt2-homologous aph1 gene in S. pombe , which encodes an enzyme relatively specific for a AppppA [ 20 ] , a 290-fold increase in AppppA concentration was observed [ 22 ] . Our data indicate that Hnt2 hydrolyzes ApppN and AppppN in vivo in budding yeast and that an intact adenine biosynthetic pathway is required for high-level synthesis and accumulation of adenylylated dinucleoside polyphosphates.

  • Increases in dinucleoside polyphosphates in Hnt2+ cultures cannot be attributed to thermal inactivation of Hnt2 because the presence of HNT2 plasmids continues to reduce incremental increases in dinucleoside polyphosphates even in the fourth hour of the heat shock.

  • HNT2 is simply control of dinucleoside polyphosphates lest their accumulation inhibit other enzymes (i.e.

  • The high levels of ApppN (~100 μM) and AppppN (~10 μM) and the fact that Hnt2-containing samples continue to reduce the rate of increase in dinucleoside polyphosphates without reducing their concentrations demonstrate that heat shock induces dinucleoside polyphosphate synthesis and that Hnt2 is saturated under such conditions.
