| Research Abstract |
For elucidation of the mechanisms of huge Complex I, locates at the entrance of the mitochondrial respiratory chains, determination of the atomic structure of the whole Complex I is essential. We have established the method for purification of intact Complex I from bovine heart and surveyed the 2-D and 3-D crystallization conditions to provide the crystals of the enzyme complex. The resonance Raman spectra of FMN in purified enzyme were determined, suggest the existence of a mechanism for prevention of spontaneous production of reactive oxygen species.
