Studium struktury a dynamiky proteinů pomocí optické spektroskopie / Study of protein structure and dynamics by means of optical spectroscopy

Title: Study of protein structure and dynamics by means of optical spectroscopy Author: Tomáš Pazderka Institute: Institute of Physics of Charles University Supervisor: RNDr. Vladimír Kopecký, Ph.D., Institute of Physics of Charles University Abstract: The aim of this thesis is to improve understanding of protein structure and dynamics and extend experimental setup and data processing for such stud- ies. We focus on the extension of experimental feasability of vibrational optical activity (VOA). We have demonstrated a usability of intensity calibration in the field of Raman optical activity. Advantages for measurements on multiple instru- ments and/or using different configurations have been shown. A new instrumental setup has been developed for microsampling measurements of vibrational circular dichroism spectra with a spatial resolution of 1 mm. Using this technique, spatial inhomogeneities in a sample of protein fibrils have been observed. Model com- pounds for amide nonplanarity have been investigated utilizing several methods of optical spectroscopy and key spectral features for determination of amide non- planarity and the absolute configuration have been identified. A comprehensive set of Raman spectra of proteinogenic amino acids has been measured. Sample concentration dependencies and consequent...
