How can you use “appppa” in a sentence? Here are some example sentences to help you improve your vocabulary:
However, deletion of lysU had no effect on heat-shock inducible AppppA accumulation [ 37 ] . The KRS1 gene [ 38 ] encoding cytosolic lysyl tRNA synthetase was cloned into multicopy plasmid pRS423 [ 39 ] to generate plasmid pM1.
If the substrate-dependent signaling model is correct, then compound 6b, as a nearly isosteric AppppA analog with a low K i , may promote Fhit signaling in Fhit+ cells.
Covalent structures of AppppA ( 1 ) and compounds 6b and 12b are provided in Figure 1.
Earlier, Blackburn and co-workers made "supercharged" methane-trisphosphonic acid AppppA analogs containing a central carbon from which three adenylate or phosphate moieties are bonded [ 15 ] . In work presented here, tripodal inhibitors 15a and 17a showed, respectively, micromolar and submicromolar efficacies while the phosphorothioate counterparts 15b and 17b showed 100 nM efficacy.
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.
