Time-Resolved Step-Scan Fourier Transform Infrared and Visible Absorption Difference Spectroscopy for the Study of Photosystem I
Step-scan Fourier transform infrared and visible absorption difference spectroscopy, with nanosecond to millisecond time resolution, has been applied to the study of photosystem I particles from photosynthetic oxygen-evolving organisms. In particular, time-reso lved infrared (1800–1200 cm21) and visible (680–850 nm) difference spectra associated with ash induced oxidation of the primary elect...
متن کاملProton Transfer and Protein Conformation Dynamics in Photosensitive Proteins by Time-resolved Step-scan Fourier-transform Infrared Spectroscopy
Monitoring the dynamics of protonation and protein backbone conformation changes during the function of a protein is an essential step towards understanding its mechanism. Protonation and conformational changes affect the vibration pattern of amino acid side chains and of the peptide bond, respectively, both of which can be probed by infrared (IR) difference spectroscopy. For proteins whose fun...
متن کاملA1 reduction in intact cyanobacterial photosystem I particles studied by time-resolved step-scan Fourier transform infrared difference spectroscopy and isotope labeling.
Time-resolved step-scan Fourier transform infrared (FTIR) difference spectroscopy, with 5 mus time resolution, has been used to produce P700(+)A(1)(-)/P700A(1) FTIR difference spectra in intact photosystem I particles from Synechococcus sp. 7002 and Synechocystis sp. 6803 at 77 K. Corresponding spectra were also obtained for fully deuterated photosystem I particles from Synechococcus sp. 7002 a...
متن کاملProbing protonation/deprotonation of tyrosine residues in cytochrome ba3 oxidase from Thermus thermophilus by time-resolved step-scan Fourier transform infrared spectroscopy.
Elucidating the properties of the heme Fe-Cu(B) binuclear center and the dynamics of the protein response in cytochrome c oxidase is crucial to understanding not only the dioxygen activation and bond cleavage by the enzyme but also the events related to the release of the produced water molecules. The time-resolved step-scan FTIR difference spectra show the ν(7a)(CO) of the protonated form of T...
متن کاملStep-scan time-domain terahertz magneto-spectroscopy.
We present a novel approach for terahertz time-domain spectroscopy of magneto-optic phenomena. The setup used in this work combines a tabletop pulsed magnet and a standard terahertz time-domain spectroscopy system. The approach is based on repetitive operation of the pulsed magnet and step-wise increment of the delay time of the time-domain spectroscopy system. The method is demonstrated by plo...
