Pepsi-SAXS: an adaptive method for rapid and accurate computation of small-angle X-ray scattering profiles
A new method called Pepsi-SAXS is presented that calculates small-angle X-ray scattering profiles from atomistic models. The method is based on the multipole expansion scheme and is significantly faster and more precise compared with the CRYSOL, FoXS and three-dimensional Zernike methods.
Structure of the family B DNA polymerase from the hyperthermophilic archaeon Pyrobaculum calidifontis
The structure of the family B DNA polymerase from the hyperthermophilic archaeon P. calidifontis has been determined with an R factor of 24.47% and an Rfree of 28.81% at 2.80 Å resolution. The enzyme has a number of unique structural features which distinguish it from other archaeal DNA polymerases.
Structural study of the X-ray-induced enzymatic reduction of molecular oxygen to water by Steccherinum murashkinskyi laccase: insights into the reaction mechanism
A series of diffraction data sets with increasing absorbed radiation dose were collected from a single crystal of S. murashkinskyi laccase at 1.35 Å resolution. The mechanism of oxygen reduction catalyzed by laccases is discussed.
1.8 Å resolution crystal structure of the carbapenem intrinsic resistance protein CarF
The crystal structure of the carbapenem-resistance protein CarF has been determined at 1.8 Å resolution. CarF confers partial intrinsic resistance to the naturally occurring antibiotic 1-carbapen-2-em-3-carboxylic acid.
