Analysis and overexpression in Escherichia coli of a staphylococcal gene encoding seryl-tRNA synthetase

Abstract

We have sequenced and expressed in Escherichia coli the gene encoding the seryl-tRNA synthetase from the pathogenic bacterium Staphylococcus aureus. The overexpressed and purified recombinant enzyme was able to aminoacylate unfractionated tRNA from E. coli. Its activity was not affected by antibodies raised against and inhibiting the E. coli seryl-tRNA synthetase.
