Quantitative assessment of oxygen availability: perceived aerobiosis and its effect on flux distribution in the respiratory chain of Escherichia coli.

abstract：:A mutant requiring isoleucine and valine for growth, because of the absence of acetolactate synthase activity, has been isolated. At least one of three different genes (ilvG, ilvB, ilvI) is required for the expression of acetolactate synthase activity, thus suggesting the presence of three different acetolactate synth...
