Course contents

The course will present a mechanistic perspective of the role of metals and metalloids in biology. After a short introduction to metal ion storage, transport, and homeostasis, the course will progress to a detailed discussion of redox metalloenzymes, particularly dioxygen metabolism. Early discussions will focus on dioxygen transport (myoglobin, hemoglobin, hemerythrin, hemocyanin), superoxide metabolism (superoxide dismutase and superoxide reductase), enzymes utilizing peroxide (peroxidases and catalases), dioxygen-activating enzymes (monooxygenases and dioxygenases), and cytochrome P450. Subsequent topics for discussion will include selected redox cofactors, particularly those present in various copper proteins, cytochromes b and c, iron-sulfur clusters, cobalamins, and molybdenum cofactors. Particular emphasis will be placed throughout on electronic-structural and mechanistic insights afforded by synthetic model systems. The course will conclude with a discussion of special topics, which will vary from year to year, depending on the interests of course participants and on recent happenings in the field. Examples of such topics include NO biology, arsenic toxicity, metallodrugs such as platinum anticancer drugs and technetium radiopharmaceuticals, aspects of the origin of life, etc.
