Activities of cofactor-deficient MoFe proteins in hydrocarbon formation. Time-dependent formation of hydrocarbon products from the reduction of CN (A) and CO (B) by ΔnifH (●), ΔnifBΔnifZ (▼), and ΔnifB (○) MoFe proteins. Activities were expressed in nanomole total reduced carbon/micromole protein, which were calculated based on the data in Fig. S2.
