| Research Abstract |
To develop new methodologies for structural analysis of biologically important high-molecular-weight protein complexes, applications of the segment label and new NMR techniques such as the transfer cross-saturation (TCS) and residual dipole coupling (RDC) were examined. By using TCS for the final electron transfer complex in the respiratory chain, the complex between cytochrome c and cytochrome c oxidase, we successfully determined the amino acid residues of cytochrome c directly interacting with cytochrome c oxidase.
