Atomic resolution structures of ribonuclease A at six pH values

Six structures of bovine pancreatic ribonuclease at six pH values have been refined and analyzed. A comparative analysis of the six models and some biological implications are discussed.

Atomic resolution data reveal flexibility in the structure of RNase Sa

The structure of recombinant RNase Sa from 1.0 Å spacing synchrotron data collected at cryogenic temperature shows two alternative conformations of the main chain in two loops which contain active-site residues. This feature was not observed in the structure refined against room-temperature data at 1.2 Å resolution.

Advantages of high-resolution phasing: MAD to atomic resolution

The structure of the endoglucanase A from Clostridium thermocellum CelA has been re-solved by three-wavelength MAD.
