Repression of the Staphylococcus aureus accessory gene regulator in serum and in vivo.

abstract：:Expression of the catalase-peroxidase of Caulobacter crescentus, a gram-negative member of the alpha subdivision of the Proteobacteria, is 50-fold higher in stationary-phase cultures than in exponential cultures. To identify regulators of the starvation response, Tn5 insertion mutants were isolated with reduced expres...
