Cel The project is aimed at the application and further development of a novel non-destructive NMR method of high sensitivity, chemical selectivity, and high spectral resolution. The method is based on chemically induced dynamic nuclear polarization (CIDNP) f or studying the structure and dynamic processes of biological macromolecules at physiological conditions. We propose to utilize the nuclear spin polarization that is formed in the reversible light-induced radical reactions of dye markers with proteins and nucleic acids and their structural subunits (amino acids, peptides, nucleotides, oligonucleotides) in aqueous solution and to expand the application of the method to similar processes in the solid state.The research methodology includes application of three types of CIDNP experiments:(i) with time-resolution,(ii) with magnetic field variation by field-cycling, and(iii) with resonant pumping of electronic spin transitions for NMR detection of EPR spectra of spin correlated radicals pairs in combination with field-cycling.The project has an interdisciplinary character and includes biological, photochemical, and physical approaches. The research activities are associated with the following:1. The study of photochemical reactions involving proteins and protein-related molecules will create a reliable basis for studying proteins using the CIDNP technique, and will contribute to the knowledge of photochemistry of biopolymers.2. The investigation of native partially folded and denatured states of proteins, as well as the study of the processes of denaturation and folding will be compared with the theoretical modelling of protein dynamics.3. Development and application of MAS-NMR detection of time evolution and field dependence of nuclear polarization in proteins in solid state.
