Expression levels of the four pyruvate-dissipating enzymes (A) and two acetyl-CoA-dissipating enzymes (B). RPKM, reads per kilobase of a gene per million mapped reads, averaged across all replicates. Designations: pdh, pyruvate dehydrogenase complex; ldh, lactate dehydrogenase; pfl, pyruvate-formate lyase; alsS, acetolactate synthase; adhE, aldehyde-alcohol dehydrogenase; pta, phosphate acetyltransferase.
