Dr. Stephen Benkovic is known for his major contributions that have initiated or shaped our understanding of biological processes. Benkovic was the first to hypothesize that conformational changes outside the enzyme’s active site were necessary for achieving maximal catalysis. This is beautifully illustrated by his studies on dihydrofolate reductase (DHFR). Benkovic showed how multi-enzyme complexes are assembled to achieve specificity and function and where several activities are present how they are mediated. This was accomplished in his studies on DNA replication that featured assembly, disassembly and function of the T4 replisome that coordinated DNA replication. Benkovic discovered the first example of a reversible metabolon, the purinosome, that only assembles in response to cellular demands and has demonstrated that the purinosome acts temporarily and spatially to form and deliver needed metabolites to cellular constituents.
