We report biochemical and structural studies on inhibiting bacterial -adenosyl-L-homocysteine hydrolase by transition metal cations. Our results revealed diverse molecular mechanisms of enzyme inactivation. Depending on the cation, the mechanism is based on arresting the enzyme in its closed, inactive conformation, disulfide bond formation within the active site or oxidation of the intermediate form of a cofactor.

Special attention is paid to pristine intrinsically conducting polymers (ICPs) and their composites with other organic and inorganic components, well-defined micro- and nanostructures, and enhanced surface areas compared with those of conventionally prepared ICPs. Hydrogels, due to their defined porous structures and being filled with aqueous solution, offer the ability to increase the amount of immobilized chemical, biological or biochemical molecules.

- - Zinc porphyrin-functionalized fullerene derivatives were created and combined with titania to form composites, which were then studied for their electrochemical properties and energy levels through various measurements.
- - Techniques like Raman, IR, and DLS were used to investigate the chemical groups on titania surfaces, along with the absorption properties and surface areas of the composites.
- - The photocatalytic efficiency of these composites was tested on pollutants like phenol and methylene blue, with the best-performing composite used for cleaning river and wastewater, while byproducts were analyzed using advanced LC-UV/Vis-MS/MS methods.
