RT   regulated by PhzR in response to cell density.";
RL   J. Bacteriol. 176:3966-3974(1994).
CC   -!- FUNCTION: Positive regulator of phenazine antibiotic production. May
CC       activate the phenazine biosynthetic genes by binding to a DNA sequence
CC       upstream of them, or to an intermediate gene which, in turn, interacts
CC       with them.
CC   -!- SIMILARITY: Belongs to the autoinducer-regulated transcriptional
CC       regulatory protein family. {ECO:0000305}.
