Obituary

Sergei Moralev (1951-2011)

Sergei N. Moralev, Doctor of Biological Sciences, the leading researcher of the I. M. Sechenov Institute of Evolutionary Physiology and Biochemistry of Russian Academy of Sciences, passed away on July 27, 2011 at the age of 60. Our science sustained a big loss of a prominent specialist in the area of evolutionary biochemistry of insects and comparative enzymology of cholinesterases, the brilliant methodologist, active experimentalist, expert scientific editor and translator.

Sergei Moralev graduated from the Leningrad University Biological department in 1974, his specialisation was biology, zoology and entomology. He worked for 8 years in the All-Soviet Institute of Plants protection, and in 1983 he joined the Institute of Evolutionary Physiology and Biochemistry where he made his carreer from trainee to leading researcher. He defended his PhD thesis in 1983 and doctorate thesis in 2005.

Scientific interests of Sergei Moralev were extremely wide. In the beginnig of his scientific career he worked as an entomologist-insecticids researcher, next he switched to comparative enzymology, kinetics of cholinesterase catalysis, mathematical methods of analysis, structural analysis of proteins and conformational structure methods — such a list could form several scientific biographies. Among the scientific interests of Sergei Moralev was comparative evolutionary research on the catalytic properties of cholinesterases of animals belonging to different stages of evolutionary development. He proposed a statistical approach for studying the structure of the active site of cholinesterases, comparing his own results with reported data about 3D structures and sequences.

Sergei Moralev wrote more than 130 scientific papers, including a 500-page textbook entitled "Comparative enzymology of cholinesterases", published in 2007 in the USA. He supervised several PhD thesis projects and graduation works.

In the past recent years S.M. Moralev actively worked as the editor of the Journal of Evolutionary Biochemistry and Physiology, also he was a highly skilled translator of biochemical papers for the English version of the Journal.

Sergei Moralev was a man of great erudition with areas of interest far broader than biological problems. He was interested both in music and military history. He had good sense of humor and easily communicated with people.

We miss him much.
