Abstract
The peroxidase activity of cytochrome (cyt) c increases when Met80 dissociates from the heme iron, which is related to the initial cyt c membrane permeation step of apoptosis. Met80-dissociated cyt c can form an oxygenated species. Herein, resonance Raman spectra of Met80-depleted horse cyt c (M80A cyt c) were analyzed to elucidate the heme ligand properties of Met80-dissociated cyt c. The Fe-His stretching (νFe-His) mode of ferrous M80A cyt c was observed at 236 cm-1, and this frequency decreased by 1.5 cm-1 for the 15N-labeled protein. The higher νFe-His frequency of M80A cyt c than of other His-ligated heme proteins indicates strong heme coordination and the imidazolate character of His18. Peaks attributed to the Fe-O2 stretching (νFe-O2) and O-O stretching (νO-O) modes of the oxygenated species of M80A cyt c were observed at 576 and 1148 cm-1, respectively, under an 16O2 atmosphere, whereas the frequencies decreased to 544 and 1077 cm-1, respectively, under an 18O2 atmosphere. The νFe-O2 mode of Hydrogenobacter thermophilus (HT) M59A cyt c552 was observed at 580 cm-1 under an 16O2 atmosphere, whereas the frequency decreased to 553 cm-1 under an 18O2 atmosphere, indicating that relatively high νFe-O2 frequencies are characteristic of c-type cyt proteins. By comparison of the simultaneously observed νFe-O2 and νO-O frequencies of oxygenated cyt c and other oxygenated His-ligated heme proteins, the frequencies tend to have a positive linear relationship; the νFe-O2 frequency increases when the νO-O frequency increases. The imidazolate character of the heme-coordinated His and strong Fe-O and O-O bonds are characteristic of cyt c and apparently related to the peroxidase activity when Met80 dissociates from the heme iron.

Abstract
Supramolecules, which are formed by assembling multiple molecules by noncovalent intermolecular interactions instead of covalent bonds, often show additional properties that cannot be exhibited by a single molecule. Supramolecules have evolved into molecular machines in the field of chemistry, and various supramolecular proteins are responsible for life activities in the field of biology. The design and creation of supramolecular proteins will lead to development of new enzymes, functional biomaterials, drug delivery systems, etc.; thus, the number of studies on the regulation of supramolecular proteins is increasing year by year. Several methods, including disulfide bond, metal coordination, and surface-surface interaction, have been utilized to construct supramolecular proteins. In nature, proteins have been shown to form oligomers by 3D domain swapping (3D-DS), a phenomenon in which a structural region is exchanged between molecules of the same protein. We have been studying the mechanism of 3D-DS and utilizing 3D-DS to construct supramolecular metalloproteins. Cytochrome c forms cyclic oligomers and polymers by 3D-DS, whereas other metalloproteins, such as various c-type cytochromes and azurin form small oligomers and myoglobin forms a compact dimer. We have also utilized 3D-DS to construct heterodimers with different active sites, a protein nanocage encapsulating a Zn-SO4 cluster in the internal cavity, and a tetrahedron with a designed building block protein. Protein oligomer formation was controlled for the 3D-DS dimer of a dimer-monomer transition protein. This article reviews our research on supramolecular metalloproteins.

Abstract
Efficient catalysis of the oxygen reduction reaction (ORR) is of central importance to function in fuel cells. Metalloproteins, such as laccase (Cu) or cytochrome c oxidase (Cu/Fe-heme) carry out the 4H(+)/4e(-) reduction quite efficiently, but using large, complex protein frameworks. Smaller heme proteins also can carry out ORR, but less efficiently. To gain greater insight into features that promote efficient ORR, we expressed, characterized, and investigated the electrochemical behavior of six new mutants of cytochrome c552 from Thermus thermophilus: V49S/M69A, V49T/M69A, L29D/V49S/M69A, P27A/P28A/L29D/V49S/M69A, and P27A/P28A/L29D/V49T/M69A. Mutation to V49 causes only minor shifts to Fe(III/II) reduction potentials (E°'), but introduction of Ser provides a hydrogen bond donor that slightly enhances oxygen reduction activity. Mutation of L29 to D induces small shifts in heme optical spectra, but not to E°' (within experimental error). Replacement of P27 and P28 with A in both positions induces a -50 mV shift in E°', again with small changes to the optical spectra. Both the optical spectra and reduction potentials have signatures consistent with peroxidase enzymes. The V49S and V49T mutations have the largest impact of ORR catalysis, suggesting that increased electron density at the Fe site does not improve O2 reduction chemistry.

Abstract
Cytochrome c (cyt c) family proteins, such as horse cyt c, Pseudomonas aeruginosa cytochrome c551 (PA cyt c551), and Hydrogenobacter thermophilus cytochrome c552 (HT cyt c552), have been used as model proteins to study the relationship between the protein structure and folding process. We have shown in the past that horse cyt c forms oligomers by domain swapping its C-terminal helix, perturbing the Met–heme coordination significantly compared to the monomer. HT cyt c552 forms dimers by domain swapping the region containing the N-terminal α-helix and heme, where the heme axial His and Met ligands belong to different protomers. Herein, we show that PA cyt c551 also forms domain-swapped dimers by swapping the region containing the N-terminal α-helix and heme. The secondary structures of the M61A mutant of PA cyt c551 were perturbed slightly and its oligomer formation ability decreased compared to that of the wild-type protein, showing that the stability of the protein secondary structures is important for domain swapping. The hinge loop of domain swapping for cyt c family proteins corresponded to the unstable region specified by hydrogen exchange NMR measurements for the monomer, although the swapping region differed among proteins. These results show that the unstable loop region has a tendency to become a hinge loop in domain-swapped proteins.

Abstract
Cytochrome c555 from hyperthermophilic bacteria Aquifex aeolicus (AA cyt c555 ) is a hyperstable protein belonging to the cyt c protein family, which possesses a unique long 310 -α-310 helix containing the heme-ligating Met61. Herein, we show that AA cyt c555 forms dimers by swapping the region containing the extra 310 -α-310 helix and C-terminal α-helix. The asymmetric unit of the crystal of dimeric AA cyt c555 contained two dimer structures, where the structure of the hinge region (Val53-Lys57) was different among all four protomers. Dimeric AA cyt c555 dissociated to monomers at 92 ± 1°C according to DSC measurements, showing that the dimer was thermostable. According to CD measurements, the secondary structures of dimeric AA cyt c555 were maintained at pH 2.2-11.0. CN(-) and CO bound to dimeric AA cyt c555 in the ferric and ferrous states, respectively, owing to the flexibility of the hinge region close to Met61 in the dimer, whereas these ligands did not bind to the monomer under the same conditions. In addition, CN(-) and CO bound to the oxidized and reduced dimer at neutral pH and a wide range of pH (pH 2.2-11.0), respectively, in a wide range of temperature (25-85°C), owing to the thermostability and pH tolerance of the dimer. These results show that the ligand binding character of hyperstable AA cyt c555 changes upon dimerization by domain swapping.

Abstract
Heme proteins perform various biological functions ranging from electron transfer, oxygen binding and transport, catalysis, to signaling. Although adopting proper native states is very important for these functions, progresses in representative heme proteins, including cytochrome c (cyt c), cytochrome b5 (cyt b5), myoglobin (Mb), neuroglobin (Ngb), cytochrome P450 (CYP) and heme-based sensor proteins such as CO sensor CooA, showed that various native functions, or new functions evolved, are also closely associated with non-native states. The structure and function relationship of heme proteins in non-native states is thus as important as that in native states for elucidating the precise roles of heme proteins in biological systems.
