  • Title: Mapping of the constitutive lysyl-tRNA synthetase gene of Escherichia coli K-12.
    Author: Emmerich RV, Hirshfield IN.
    Journal: J Bacteriol; 1987 Nov; 169(11):5311-3. PubMed ID: 3312173.
    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.
