Species-specific repetitive extragenic palindromic (REP) sequences in Pseudomonas putida.

ABSTRACT: Pseudomonas putida KT2440 is a soil bacterium that effectively colonises the roots of many plants and degrades a variety of toxic aromatic compounds. Its genome has recently been sequenced. We describe that a 35 bp sequence with the structure of an imperfect palindrome, originally found repeated three times downstream of the rpoH gene terminator, is detected more than 800 times in the chromosome of this strain. The structure of this DNA segment is analogous to that of the so-called enterobacteriaceae repetitive extragenic palindromic (REP) sequences, although its sequence is different. Computer-assisted analysis of the presence and distribution of this repeated sequence in the P.putida chromosome revealed that in at least 80% of the cases the sequence is extragenic, and in 82% of the cases
