Cytochrome c: A Multifunctional Protein Combining Conformational Rigidity with Flexibility
Figure 21
Crystal structures of oxidized monomeric and oligomeric cyt-c. (a) Structure of monomeric cyt-c (PDB ID code 1HRC). (b) Structure of dimeric cyt-c (red and blue). (c) Structure of trimeric cyt-c (red, blue, and green). The hemes are shown as gray stick models. Side-chain atoms of M80 are displayed as yellow stick models. The N and C termini and the N- and C-terminal helices are labeled as N, C, , and , respectively. The T79-A83 residues (hinge loop of the monomer) are depicted in pale colors.
