The aim of research and our major interests:

Plant lipoxygenases. Studies of the molecular mechanisms of catalysis and the search for new physiologically active products.

Areas of current interest:

Studies of the plant lipoxygenase signaling cascade, including search for new signal mediators, elucidation of their biosynthetic pathways and mechanisms, as well as their role in reprogramming of the genome expression and protein synthesis;

Studies of the molecular mechanisms of catalysis of enzymes from CYP74 family, including identification of the primary determinants of catalysis.

To study metabolism of polienoic fatty acids and their hydroperoxides, we use enzymes isolated from plant tissues as well as recombinant enzymes (lipoxygenases and CYP74 cytochrome family) and their mutant forms prepared by site-directed mutagenesis.
