Neutron Diffraction Studies of Bacteriorhodopsin Structurees a specialized region in the plasma membrane that converts visible light energy into an electrochemical gradient by pumping protons across the plasma membrane out of the cell (2). This specialized membrane can be isolated in a stable form at low ionic strength (3,4) and is known as the purple memb

A Protein Structure is Only as Good as the Data and atomic species. In the neutron case, it is possible to localize hydrogen atoms (1). This, however, just about doubles the total number of atoms to be derived with about the same number of reflections. In addition, neutron data are often of poorer statistical quality than their x-ray counterpart

Hydrogen Bonding and Exchange in Oxymyoglobine subunit of a hemoglobin (Hb) tetramer. In oxygenated myoglobin (oxyMb), the iron atom is coordinated by four porphyrin nitrogen atoms, N. of the invariant “proximal” histidine (His 8F), and an oxygen molecule (19). A second histidine (His 7E), the “distal” histidine, lies close to the oxygen, and

Deuterium Exchange in Lysozyme at 1.4-Å Resolutioned in at least seven crystalline forms. The mechanism of action of lysozyme in cleaving the muco-polysaccharides of certain bacterial cell walls is now well understood, largely as a result of crystallographic investigations; see Imoto et al. (5) for a review. While crystallographic work continues in
