The to 70th birthday of Academician of the National Academy of Sciences of Ukraine S. O. Kosterin

Serhiy Kosterin is a renowned biochemist and biophysicist, full member of the National Academy of Sciences of Ukraine, professor, laureate of the State Prize of Ukraine in science and technology. The academic research interests of Prof. S.O. Kosterin include a wide range of current problems of biochemistry, biophysical chemistry, biophysics and molecular physiology, with a special focus on enzymology, biomembranology, intracellular calcium homeostasis, electro- and pharmacomechanical coupling in myocytes, as well as the kinetics of biochemical reactions. Prof. Kosterin devotes a great deal of efforts to develop new methods of kinetic analysis of complex biochemical and biophysical processes, such as enzymatic catalysis, membrane transport, receptor-ligand interaction, intracellular calcium signaling, muscle contraction-relaxation. In co-operation with colleagues, Serhiy Kosterin developed a mathematical model of intracellular calcium homeostasis in smooth muscles. He carried out an analysis of thermodynamic behavior specific for the “enzyme-substrate-reversible effector” system; proposed a universal method for studying the mechanism of action of the reversible inhibitor in the system “enzyme/transport protein – transported substrate/substance – reversible inhibitor”; developed the thermodynamic theory of the formation of the Gibbs-Donnan potential in the “membrane vesicles – dilution medium” system. Prof. Serhiy Kosterin meets his 70th birthday in the full bloom of life and with grandiose plans.
