Propylene formation from CO2 and acetylene as a function of electron flux. The amount of propylene formed as a function of electron flux is shown for the α-70Ala/α-195Gln MoFe protein. The partial pressure of CO2 was 0.45 atm and C2H2 was 0.014 atm. The concentration of MoFe protein was 0.5 mg/mL, and Fe protein was varied from 0.25 to 3 mg/mL. The reactions were incubated at 30 °C for 60 min. Inset shows the CH4 production as a function of electron flux.
