Model of Geobacter spp. oxidative metabolism coupled to soluble extracellular metal reduction

Here is a model of the extracellular metal reduction ring and oxidative metabolism ring within the Geobacter circus.

Inner and outer membrane protein components of the Geobacter oxidative metabolism complexes (right 4 protein models on bottom) with MacA (lower left) for metal reduction, periplasmic cytochrome PpcA and the outer membrane proteins, OmcF, OmcS, and OmcZ. Coloring is by hydrophobicity.
