Journal ArticleDOI
Protonation state and structural changes of the tetrapyrrole chromophore during the Pr --> Pfr phototransformation of phytochrome: a resonance Raman spectroscopic study.
TL;DR: The photoconversion of phytochrome from the inactive (Pr) to the physiologically active form (Pfr) was studied by near-infrared Fourier transform resonance Raman spectroscopy at cryogenic temperatures, which allow us to trap the intermediate states.
Journal ArticleDOI
Investigations Into the Drug-Drug Interaction Potential of Tapentadol in Human Liver Microsomes and Fresh Human Hepatocytes
TL;DR: The new analgesic tapentadol was evaluated for induction and inhibition of several cytochrome P450 enzymes in vitro, and protein binding was assessed.
Journal ArticleDOI
Raman spectroscopic and light-induced kinetic characterization of a recombinant phytochrome of the cyanobacterium Synechocystis.
Anja Remberg,Ingo Lindner,Tilman Lamparter,Jon Hughes,Christa Kneip,Peter Hildebrandt,Silvia E. Braslavsky,Wolfgang Gärtner,Kurt Schaffner +8 more
TL;DR: The Raman spectra suggest far-reaching similarities in chromophore configuration and conformation between the Pfr forms of Synechocystis phy tochrome and the plant phytochromes, but some differences, such as torsions around methine bridges and in hydrogen bonding interactions, in the Pr state.
Journal ArticleDOI
Interpretation of the resonance Raman spectra of linear tetrapyrroles based on DFT calculations
TL;DR: In this paper, the Raman spectra of linear methine-bridged tetrapyrroles in different conformational and protonation states were calculated on the basis of scaled force fields obtained by density functional theory.
Journal ArticleDOI
Fourier transform near-infrared resonance Raman spectroscopic study of the α-subunit of phycoerythrocyanin and phycocyanin from the cyanobacteriumMastigocladus laminosus
Christa Kneip,Axel Parbel,Harald Foerstendorf,Hugo Scheer,Friedrich Siebert,Peter Hildebrandt +5 more
TL;DR: In this article, the isolated α-subunits of the light-harvesting pigments phycoerythrocyanin (PEC) and C-phycocyanin (CPC) of Mastigocladus laminosus were studied by resonance Raman (RR) spectroscopy.
