Example sentences for: dinucleoside
How can you use “dinucleoside” in a sentence? Here are some example sentences to help you improve your vocabulary:
An added benefit of these constructions is the availability of yeast strains that possess high levels of dinucleoside polyphosphates and at the same time express a mutant Fhit-homologous protein, because these are conditions which have been postulated to constitute the signaling form of Fhit [ 16 ] . Finally, using controlled genotypes we revisited conditions that lead to increased accumulation of dinucleoside polyphosphates [ 24 25 26 27 28 29 30 31 32 33 ] . Recognizing that hnt2 deletion is a pathological condition, we were particular interested in identifying conditions that lead to accumulation of such compounds in cells that contain a functional HNT2 gene, rather than simply identifying conditions that produce diadenosine polyphosphate accumulation in the absence of 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.
Strain BY71-6c was transformed with plasmids pRS423 and pM1 (multicopy KRS1 ) and cultures were grown as for measurement of dinucleoside polyphosphate levels.
This reduction was active-site dependent: adding back multicopy HNT2 with the nucleophilic histidine replaced by alanine or aspartate reduced dinucleoside polyphosphate levels less than two-fold.
To survey dinucleoside polyphosphate induction as a function of potential stress conditions, strain BY71-6c was transformed with either pRS423 or pM1 (effectively hnt2Δ and hnt2Δ YEp KRS1 , respectively) and strain BY71-16d was transformed with the same plasmids (effectively HNT2Δ and HNT2Δ YEp KRS1 , respectively).
