Conformational changes in FmetHbS probed with UV resonance Raman and fluorescence spectroscopic methods
Article Abstract:
Research was conducted to examine the tertiary and quaternary structure of HbS by UV resonance Raman and fluorescence spectroscopic approaches. The study was conducted using the tetrameric form as the fluoromet derivative and compared with HbA under the same conditions. Combined spectroscopic experiments revealed an altered tertiary structure in HbS where the A-helix is displaced toward the E-helix as monitored by the strength of the beta-15 Trp***beta72 Ser H-bond.

The active site structure of heme a(sub 3)(super 3+)-C (triple bond) N-Cu(sub B)(super 2+) of cytochrome aa(sub 3) oxidase as revealed from resonance Raman scattering
Article Abstract:
The structure of the heme a(sub 3)-C (triple bond) N-Cu(sub B) complex of the oxidized cytochrome aa(sub 3) oxidase is studied. The resonance Raman and FTIR spectroscopies are used to discuss the properties of the complex.
