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.

defined in [17]. Potentials are the arithmetic mean of values in the
database.
