Contributions of discrete tRNA(Ser) domains to aminoacylation by E.coli seryl-tRNA synthetase: a kinetic analysis using model RNA substrates.

abstract：:The study of bacterial isolates or communities requires the analysis of the therein included plasmids in order to provide an extensive characterization of the organisms. Plasmids harboring resistance and virulence factors are of especial interest as they contribute to the dissemination of antibiotic resistance. As the...
