A, transcript fold changes in central metabolism of nitrogen starvation-induced resting compared with exponentially growing B. subtilis wild-type cultures. B, kinetics of PgapB promoter activity in B. subtilis wild-type (black circles) and yqfL mutant (open circles) upon entry into nitrogen starvation of PgapB-gfp carrying strains. G6P, glucose 6-phosphate; DHAP, dihydroxyacetone phosphate; E4P, erythrose 4-phosphate; F6P, fructose 6-phosphate; PGA, phosphoglycerate; PEP, phosphoenolpyruvate; P5P, pentose 5-phosphate; S7P, sedoheptulose 7-phosphate; N, nitrogen.
