Rossmann (1930-2019) A towering figure of molecular biophysics Celerino Abad-Zapatero, University of Illinois at Chicago, IL (USA) . ICHAEL G. ROSSMANN, a towering figure in structure biology, was scheduled to give a plenary lecture at the 69th Annual Meeting of the American M Crystallographic Association – ACA in Covington, Kentucky on July 20th. His unexpected passing (May 14th, 2019 in West Lafayette, IN, USA) changed the lecture into a celebration of his scientific legacy with contributions from former students, postdocs, colleagues and the macromolecular crystallography community at large [1]. For students, postdocs and even younger practitioners of macromolecular crystallography, the name of MICHAEL ROSSMANN may bring associations with obscure Michael G. Rossmann references in technical journals of crystallography, or more recently, reference to X-ray (1930-2019). structures of large biological assemblies (i.e. viruses) and spectacular cryo-EM image reconstructions, without truly appreciating the monumental contributions that this premier figure of the field has made since the very early days of protein crystallography. MICHAEL, and physicists such as JOHN D. BERNAL, FRANCIS H. CRICK and others, established the methods and the physico-chemical basis for the interpretation of biological phenomena in terms of the atomic structures of the constituent macromolecules: they provided the framework for molecular biophysics. Fortunately, a selection of MICHAEL’s papers with some biographical notes and commentaries was published a few years ago [2], where the younger ‘apprentices’ of the field can appreciate his monumental contributions.

  • Michael Rossmann
    • • Purdue College of Science | Spring 2017 MICHAEL ROSSMANN: HIS PATH TO PURDUE & DECADES OF DISCOVERY @PurdueScience INSIDE: ARTIFICIAL INTELLIGENCE :: ALUMNUS’S NEXT NASA MISSION Dr.JD For more than 50 years, Michael Rossmann, the Hanley Distinguished Professor of Biological Sciences, walked to his labs in Lilly Hall and Hockmeyer Hall of Structural Biology from his West Lafayette home. It was a leisurely 30 -minute stroll, at just over a mile to the southern tip of the Purdue campus. However, if one adds up all of his trips, he has traveled a distance equal to a round trip to Rio de Janeiro, Brazil, and back again to Rio. During those walks down Grant Street — past the blocks of homes built in the early 20th century as Purdue University grew and through an expanding campus — Rossmann’s mind stormed with ideas. Ideas mulled on these walks have led to monumental discoveries in the field of structural biology. Rossmann’s discoveries have helped doctors under - stand, treat and even cure infections from alpha viruses, coxsackievirus B3, flaviviruses like dengue and Zika, and even the rhinovirus that causes the common cold. His latest work has been a collaborative effort with Richard Kuhn, professor of biological sciences and director of the Purdue Institute for Inflammation, Immunology and Infectious Disease, to study Zika virus. The virus has received widespread attention because of an increase in microcephaly — a birth defect that causes brain damage and an abnormally small head in babies born to some mothers infected during pregnancy — and reported transmission of the mosquito -borne virus in 33 countries.

Michael George Rossmann, who made monumental contributions to science, passed away peacefully in West Lafayette, Indiana on 14 May 2019 at the age of 88, following a courageous five-year battle with cancer. Michael was born in Frankfurt, Germany on 30 July 1930. As a young boy, he emigrated to England with his mother just as World War II ignited. Michael was a highly innovative and energetic person, well known for his intensity, persistence and focus in pursuing his research goals. Michael was a towering figure in crystallography as a highly distinguished faculty member at Purdue University for 55 years. Michael made many seminal contributions to crystallography in a career that spanned the entirety of structural biology, beginning in the 1950s at Cambridge where the first protein structures were determined in the laboratories of Max Perutz (hemoglobin, 1960) and John Kendrew (myoglobin, 1958). Michael’s work was central in establishing and defining the field of structural biology, which amazingly has described the structures of a vast array of complex biological molecules and assemblies in atomic detail.

  • In Memory of Michael G. Rossmann: a Wise Man with a Forever Young Heart
    viruses Obituary In Memory of Michael G. Rossmann: A Wise Man with a Forever Young Heart Chuan (River) Xiao Department of Chemistry and Biochemistry, University of Texas at El Paso, El Paso, TX 79968, USA; [email protected] Whenever I think about Michael’s passing, a sad feeling still strikes me. Two months before his eighty-ninth birthday, Michael left us and his beloved scientific research. His legendary achievements have been reviewed in several memorial articles [1–3]. Thus, I will not repeat here what has already been well written. Instead, I want to remember Michael as a great human being, whose impact touched many. Before I met Michael, I read his seminal publication on the glyceraldehyde 3-phosphate dehydrogenase (GAPDH) structure. I used that structure as a template to model Rice GAPDH, which I manually sequenced in China. Therefore, I felt so lucky when I joined Michael’s group in 1998. I still remember the very first thing Michael taught me: “do not call me Professor Rossmann; call me Michael.” He described the historical association with the title “Professor” in the UK, stating that he would rather earn respect from his knowledge not his title. In the introductory lecture to my large undergraduate biochemistry classes, I always relay this story and tell my students that they can call me by my first name, River. This is just one example of how Michael influenced the culture at Purdue, where it is common for students to address professors by their first names, which is not the normal practice at many other places.

Personal Statement Michael Chapman is a biophysicist who develops and applies multi-disciplinary approaches to viral-host inter- actions and enzyme mechanism/dynamics. His research group combines structural techniques: x-ray diffract- ion, electron microscopy (EM) and NMR with biochemical kinetics, molecular virology and computer modeling to understand the functional workings of large and dynamic complexes. He has had a long-standing interest in methods to optimize structural models using diverse experimental restraints from crystallography, EM and NMR, as well as stereochemical restraints from implicit-solvent electrostatics and hydrogen-bonding. Such multi-disciplinary approaches are used to advance our fundamental understanding of enzyme turnover kinetics, and to understand virus-host interactions central to the development of improved vectors for human gene therapy.

Received: 28 August 2020; Accepted: 21 September 2020; Published: 24 September 2020 Abstract: Structural virology reveals the architecture underlying infection. While notably electron microscopy images have provided an atomic view on viruses which profoundly changed our understanding of these assemblies incapable of independent life, spectroscopic techniques like NMR enter the field with their strengths in detailed conformational analysis and investigation of dynamic behavior. Typically, the large assemblies represented by viral particles fall in the regime of biological high-resolution solid-state NMR, able to follow with high sensitivity the path of the viral proteins through their interactions and maturation steps during the viral life cycle. We here trace the way from first solid-state NMR investigations to the state-of-the-art approaches currently developing, including applications focused on HIV, HBV, HCV and influenza, and an outlook to the possibilities opening in the coming years.
