Abstract excerpt
The nucleotide sequence of rpoS, the gene for the stress sigma factor, was determined in 13 different K12 strains of Escherichia coli. The results indicate that the original K12 isolate carried an amber mutation at codon 33, which in 50% of the derivatives is mutated by a single base substitution to a coding triplet, in most cases to CAG encoding glutamine. The six non-K12 strains examined here had GAG, encoding...
