Fig 4. (A) Cytosolic propionaldehyde concentrations (Acyto) with and without MCPs and MCP propionaldehyde concentrations (AMCP) with MCPs and (B) steady-state fluxes through PduP/Q and propionaldehyde leakage across the cell membrane with and without MCPs.
The baseline external 1,2-PD concentration is shown with a black dashed line; the KM of PduP/Q is shown in (A) with a black solid line.
