Cytochrome c: A Multifunctional Protein Combining Conformational Rigidity with Flexibility
Figure 8
Representations of (a) in-plane and (b) out-of-plane deformations of the porphyrin macrocycle, classified in terms of the irreducible representations of the point group. Each of these deformations reflects the normal coordinate pattern of the lowest frequency mode of the respective symmetry. Taken form [67] and modified.
