Figure 4. Network of redox active modules where the nodes are modules that share common and structural similarity [16, 17, 71], and the edges are connections between modules that are within the same protein and are capable of electron transfer between each module. Node colors represent a gradient of average redox potentials for each module. Gray edges are connections between modules without associated redox potentials within ProtReDox, and black edges are between modules with reported potentials. Node sizes are porportional to the number of redox potentials for each module. Nodes with greater than one measurement are shown. Size of the node is proportional to the number of experimental redox potentials for each node. Labeled nodes represent the redox-active cluster type: SF4 (85, 539, 1475, 1479), FES (537, 538, 539), Flavin (7, 8, 2266, 2269, 2280), heme (130, 131, 140, 421, 1737, 1746), Mo (16), and Cu (24, 72). See Table 1 for values.
