Comments by Robert B. Gennis and Jonathan P. Hosler

Working with bacterial cytochrome oxidases, the authors--from three different laboratories--have made inroads into understanding the structure of the active site of an important energy-generating protein. The protein couples electron transport to proton pumping across membranes in living systems.

"This paper was the first to provide an empirically based, three-dimensional model of the portion of the enzyme where metals bind--namely its active site," says Robert Gennis, a professor of biochemistry and chemistry at the University of Illinois, Urbana-Champaign.
