A Shift in Central Metabolism Accompanies Virulence Activation in Pseudomonas aeruginosa.

abstract：UNLABELLED:In the model eukaryote Saccharomyces cerevisiae, the transcription factor Cst6p has been reported to play important roles in several biological processes. However, the genome-wide targets of Cst6p and its physiological functions remain unknown. Here, we mapped the genome-wide binding sites of Cst6p at high r...
