Growth phase-dependent expression profiles of three vital H-NS family proteins encoded on the chromosome of Pseudomonas putida KT2440 and on the pCAR1 plasmid.

The amount of TurB increases as TurA decreases, and the amount of Pmr does not affect the amounts of TurA and TurB. This is consistent with our previous observation that TurA and TurB play complementary roles, whereas Pmr works relatively independently. This study provides insight into the molecular mechanisms underlying reconstitution of the transcriptional network in KT2440 by pCAR1 carriage.
