title: A biographical sketch of Charles F. Yocum: ;;It's the biochemistry, stupid''.
abstract: Charles F. Yocum has been a leader in the applications of biochemical techniques to the resolution and reconstitution of Photosystem II. His formal science education began as an undergraduate in biochemistry at Iowa State University and continued with graduate work in photosynthesis, first at the Illinois Institute of Technology and later at Indiana University. Following postdoctoral work at Cornell University, he joined the faculty of the University of Michigan where he has remained throughout his academic career. Charlie's contributions to a biochemical understanding of photosynthesis, particularly Photosystem II have been considerable, but most notably include his initial isolation of the first highly active oxygen-evolving particle from higher plant chloroplasts, the well-known and widely utilized 'BBY particles'. In the aftermath of that isolation, Charlie's research further resolved these particles into ever finer and simpler, but active, Photosystem II complexes. In addition, Charlie's research has provided significant insight into the roles of both Cl(-) and Ca(2+) as required cofactors in photosynthetic oxygen evolution.
