After growth at 37°C with vigorous shaking, cells were diluted ten times in fresh pre-warmed minimal medium and samples were harvested after a period of 30 minutes [C30] , i.e. before maximal induction of competence, and after a period of 90 minutes [C90], i.e. when competence induction was maximal.
	(dia15) Diamide was added to an exponentially growing culture (OD600 approx. 0.6) at a sub-lethal concentration(0.5 mM) and growth continued at 37°C with vigorous shaking. Samples were collected 0, 5 and 15 minutes after diamide addition [dia0, dia5 and dia15].
