Аннотация:This paper honors the legacy of Professor Andrei Vinogradov, a prominent Russian biochemist whose pioneering work in bioenergetics has had a lasting impact on the field of mitochondrial biochemistry.Andrei’s scientific career started at Moscow State University in 1964, during the former USSR. He later pursued postdoctoral training in the laboratories of the world-known figures in bioenergetics—Britton Chance, Efraim Racker, and Thomas Singer – where he focused on purifying and characterizing mitochondrial membrane proteins. In the 1970s, Vinogradov established a laboratory at theBiochemistry Department of Moscow University. Overthe years, his research group performed extensivestudies of key mitochondrial membrane enzymes,including succinate dehydrogenase, calciumtransporters, ATP synthase, and Complex I.This tribute, composed by his colleagues andformer students, honors Andrei Vinogradov’sextraordinary contributions to mitochondrialbiochemistry and the enduring impact he left on the bioenergetics community.
