Software tools for generating, optimizing, handling, storing and displaying macromolecular envelopes (masks) are described.
research papers
An algorithm for reconstructing macromolecular envelopes from solvent contrast variation data is described and illustrated by simulations.
research papers
Open access
A phasing algorithm for protein crystallography using diffraction data from multiple crystal forms is proposed. The algorithm is evaluated by simulation, and practical aspects and potential for ab initio phasing are discussed.
research papers
This paper describes the development of the FSEARCH program for locating envelopes in the unit cell and possible ways to extend phases to crystallographic data resolution.
research papers
New insights are provided into the uniqueness of the macromolecular crystallographic phase problem and its relationship to single particle imaging.
research papers
The feasibility of low-resolution phasing via the single isomorphous replacement method from protein powder data is demonstrated.
research papers
Open access
The design and performance of the new multi-axis goniometer PRIGo developed at the Swiss Light Source at Paul Scherrer Institute is described.
research papers
Open access
Atomistic simulations enhance protein crystallography, yielding mechanistic insights into a protein kinase involved in the regulation of fundamental biological processes that include metabolism, development, memory and immune response.
research papers
In this work, a novel method to recover the diffraction phase independently using the low-resolution data is proposed. It has been verified and found to be useful and practical using several typical examples. In addition, a practical metric has been established to determine whether the algorithm converges to a correct solution by estimating the entropy of the final results.
research papers
A generalized likelihood-based search can be used for determining the position of a macromolecule in the cell. In some cases, spurious maxima are eliminated and the signal-to-noise ratio is enhanced in comparison with the straightforward R-factor-based search.
