Aleksey Bogdanov

Alexei Alexeevich Bogdanov (born October 11, 1935, in Moscow) is a Soviet and Russian chemist and molecular biologist, Academician of the Russian Academy of Sciences (since 1994); Corresponding Member of the USSR Academy of Sciences (1984–1994). Professor and (from 1985 to 2010) head of the Department of Chemistry of Natural Compounds at the Faculty of Chemistry, M.V. Lomonosov Moscow State University (MSU). He specializes in bioorganic chemistry and molecular biology and made fundamental contributions to understanding the structure and function of ribosomes, the interaction of nucleic acids with proteins, and the mechanisms of protein biosynthesis.

Biography

International Recognition and Leadership In 1984, he was elected Corresponding Member of the USSR Academy of Sciences. In 1994, he was elected Academician of the Russian Academy of Sciences (RAS). From 1985 to 2010, he headed the Department of Chemistry of Natural Compounds at the Faculty of Chemistry of Moscow State University. At the A.N. Belozersky Research Institute of Physico-Chemical Biology, Bogdanov served as Department Head until 2002, deputy director of the institute, and from 2001 onwards as Principal Research Fellow in the same department.

He served as visiting professor at Harvard University (1966–1967), the Massachusetts Institute of Technology (MIT) (1976–1977), universities in Italy (1986, 1993), and Bulgaria (1978, 1988).

He is a member of the Russian Society of Biochemists and Molecular Biologists; a member of the European Academy of Sciences and its Presidium (since 2000); a foreign member of the Academy of Sciences of Lithuania (since 2002); a member of the Harvard Chemists Society; an honorary consultant of the International Institute of Molecular and Cellular Biology (Warsaw, Poland); a member of the expert council of the Federation of European Biochemical Societies (FEBS) (2002–2006).

Scientific research Bogdanov's scientific career, spanning over six decades, was characterized by contributions to understanding the structure and function of the ribosome. He is the author and co-author of more than 270 scientific publications, 5 monographs, and 3 textbooks.

Covalent Compounds of Nucleic Acids with Proteins Bogdanov's primary research direction involved studying complexes of nucleic acids with proteins. One of his most significant achievements was demonstrating in the early 1960s the existence of natural covalent compounds of nucleic acids with proteins for both DNA and high-molecular-weight RNA. Based on experimental data, he proposed that natural preparations of nucleic acids contain a protein fraction that could be covalently bound to DNA and RNA rather than merely adsorbed on their surface. Subsequently, jointly with Zoe Shabarova, the principal synthesis methods for such compounds were developed.

Functional Centers of the Ribosome Bogdanov developed and applied the photoaffinity modification method — a technique in which a photosensitive group is attached to a functional ligand. When such a ligand binds to the ribosome, it is irradiated with UV light, leading to formation of a covalent bond between the ligand and nearby nucleotides or amino acid residues of the ribosome. Using this method, key elements of the ribosomal decoding center — the site where genetic information is read from messenger RNA and where high-fidelity codon–anticodon recognition occurs between mRNA and transfer RNA — were identified.

Studies of the Ribosomal Tunnel In the early twenty-first century, Bogdanov focused on investigating the ribosomal tunnel — a channel inside the large ribosomal subunit through which the growing polypeptide chain passes during protein biosynthesis. His laboratory conducted detailed investigations of how tunnel structure affects the elongation process, how various translation inhibitors interact with the tunnel, and how the tunnel participates in translation regulation. Publications on this topic have practical significance for developing new antibiotics and understanding mechanisms of microbial resistance to antimicrobial agents.

From 2013 to 2023, Bogdanov headed the research project 'Design and production of antibacterial substances based on structural analysis of ribosomes. DNA aptamers as promising therapeutic agents.'

Pedagogical activity Among Bogdanov's students were more than 11 Doctors of Science (D.Sc.) and more than 40 Candidates of Science (Ph.D.).

He was deputy chief editor of the journal Biochemistry (Biokhimiya). In 2020, the journal organized a special issue dedicated to Bogdanov's jubilee.
