Figure 4
Proposed pathways for electron transfer from PQQ to cytochrome cL (shown in yellow) and proton translocation from PQQ to the periplasm (shown in red). Both pathways are predicted on the basis of the structures of the quinohaemoprotein alcohol dehydrogenase from the bacterium C. testosteroni (Oubrie et al., 2002  ). The electrons originating from oxidation of methanol would travel from the PQQ cofactor into the adjacent disulfide and then towards Asn52 or the water molecules 599 and 904 and thence to cytochrome cL. The putative proton-transfer pathway involves the side chains of a number of acidic and basic residues as well as active-site water molecules. |
