title: Improved mapping of the tyrS locus in Escherichia coli.
abstract: A tyrosyl-tRNA synthetase mutant of Escherichia coli was isolated and the tyrS gene assigned a map position between man and pdxH at 36.0 min on the chromosome. The tyrS mutant grew badly on broth as did previously described tyrS mutants. This sensitivity to broth was suppressed by tyrR mutations. F-prime factors were found to complement the tyrS mutation.
