NADP⁺-reducing (NADPH-producing) enzyme activities in glycerol-respiring (blue circles) and glucose-fermenting (brown squares) chemostats of strain EXF-4126. (A–D) Enzyme activities of 4 to 11 individual sample replicates (colored dots) and their averages (circles and squares). Measured IDH activity for glucose-grown cells is assumed to represent mIDH as the cytosolic form is glucose repressed (33). (E) Total NAPDH production rates and 1 SD propagated errors, assuming comparable total protein extract efficiencies across enzyme assays. All linear regressions are based on averages with adjusted R². See Datasets S1–S4 for details.
