Fig. 4From: Metabolic and proteomic analyses of product selectivity and redox regulation in Clostridium pasteurianum grown on glycerol under varied iron availabilityExpression patterns of enzymes catalyzing the conversion of pyruvate to acetyl-CoA under Fe+ and Fe− conditions at exponential growth phase (early) and stationary phase (late). PFOR 1 (F502_07648, pyruvate: ferredoxin oxidoreductase) and PFOR 2 [F502_07643, pyruvate:ferredoxin (flavodoxin) oxidoreductase] are up-regulated at Fe+ ; PFL (pyruvate formate lyase) is up-regulated at Fe−Back to article page
