Abstract: | The constitutive lysyl-tRNA synthetase gene (lysS) was mapped at 62.1 min on the Escherichia coli chromosome by a combination of conjugation and transduction, with physical confirmation by two-dimensional gel electrophoresis. Revertant analysis suggests that the altered isoelectric point and the low amount of the mutant LysS protein may be due to a single mutational event. |
