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.
Covalent structures of AppppA ( 1 ) and compounds 6b and 12b are provided in Figure 1.
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.
Phosphorothioate analogs 6b and 12b that preserve the α-β bridging oxygen but substitute carbon for the β phosphorus, achieving 65 to 75-fold binding advantages over AppppA, are expected to be critical for cell biological characterization.
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.
