Nucleotide sequence and deduced amino acid sequence of kpsK54D, kpsK54M, kpsK54T, and kpsK54E. Arrows identify putative transcriptional start sites, solid triangles identify the insertion site of active TnphoA fusions, the open triangle identifies the insertion site of an inactive TnphoA fusion, and the underlined regions identify the inverted repeats of a strong theoretical rho-independent RNA polymerase terminator. The JUMPstart site, the truncated kpsM (kpsMtruncated), and ISCP9110 are marked and identified by the dotted lines.
