In this article I review the history of research on the Fenna–Matthews–Olson (FMO) protein with emphasis on my contributions. The FMO protein, which transfers energy from the chlorosome to the reaction center in green sulfur bacteria, was discovered in 1962 and shown to contain bacteriochlorophyll a. From the absorption and circular dichroism spectra, it… (More)
The relative positions of the centers of mass of the 21 proteins of the 30S ribosomal subunit from Escherichia coli have been determined by triangulation using neutron scattering data. The resulting map of the quaternary structure of the small ribosomal subunit is presented, and comparisons are made with structural data from other sources.
As the first International Tables volume devoted to the crystallography of large biological molecules, Volume F is intended to complement existing volumes of International Tables for Crystallography. A background history of the subject is followed by a concise introduction to the basic theory of X-ray diffraction and other requirements for the practice of… (More)
The locations of hydrogen and deuterium atoms and water molecules have been investigated in carbon monoxide myoglobin using neutron diffraction, and the results are compared with earlier work on metmyoglobin. Parallel real space refinements on the two molecules show relatively few changes, but do show the carbon monoxide molecule with the iron atom moving… (More)
The Protein Crystallography Station at Los Alamos Neutron Science Center is a high-performance beamline that forms the core of a capability for neutron macromolecular structure and function determination. This capability also includes the Macromolecular Neutron Crystallography (MNC) consortium between Los Alamos (LANL) and Lawrence Berkeley National… (More)
Although hydrogens comprise half of the atoms in a protein molecule and are of great importance chemically and structurally, direct visualization of them by using crystallography is difficult. Neutron crystallography is capable of directly revealing the position of hydrogens, but its use on unlabeled samples faces certain technical difficulties: the large… (More)
