文摘
- •
G. sulfurreducens electron transfer pathways vary with redox potential.
- •
CbcL is a putative inner membrane multiheme cytochrome quinone oxioreductase.
- •
Deletion of cbcL impaired reduction of only low potential electron acceptors.
- •
ΔcbcL cyclic voltammetry is specifically altered near − 0.15 V vs. SHE.
- •
Data is consistent with 3 inner membrane pathways active at different potentials.
