Example sentences for: appppn

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

  • Earlier, hnt2 deletion was reported to increase AppppN levels only 2.5-fold but the study was performed in ade2 mutants [ 13 ] . Consistent with that report, the three hnt2 ade2 strains showed only a 2-fold higher AppppN level than the three HNT2 ade2 strains, when nucleotide levels were averaged across the three time points.

  • Heat shock was the best inducer of AppppN.

  • As with other experiments, AppppN levels were lower than ApppN levels in all cases.

  • Larger increases in AppppN concentrations have been seen with disruption of Apa1 and Apa2, the diadenosine tetraphosphate phosphorylases in S. cerevisiae [ 34 35 ] , indicating that they have a more significant role in controlling AppppN levels than does Hnt2.

  • 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.
