Figure 1

Physical map of the 4.4 kb EcoRI DNA fragment containing the lon protease cloned from the chromosome of P. putida WCS358. Position of the first and last nucleotide of the lon gene are shown together with the position of the Tn5 insertion. The ORF or part of ORFs downstream the lon gene display 88% and 92% similarity to the pp_2303 and pp_2304 ORFs of P. putida KT2440. In the upstream region of the lon gene, part of clpX ORF is localized.
