A new regulator gene named pltZ, which is located downstream of the plt gene cluster in the genome of Pseudomonas sp. M 18, was identified, sequenced and characterized in this report. The deduced amino acid sequence of PltZ shares significant homology with other bacterial regulators in the TetR family. The chromosomal pltZ disruption mutant gave rise to 4.4-fold enhancement of pyoluteorin biosynthesis but did not exert significant influence on the accumulation of phenazine-1-carboxylic acid compared with the wild-type M18. The negative regulation of pltZ on pyoluteorin biosynthesis was further confirmed by multiplied pltZ gene dosage experiments and pltA'-'lacZ translational fusion analyses.
