Web14. apr 2024 · The octamer model was subjected to two cycles of auto-refinement with phenix.real_space_refine 97 (with NCS constraints and NCS refinement) and local map sharpening using LocSCALE 98 (version 0.1). WebThis small molecule can be modeled as either a propionate or a glycinate. The complex is reminiscent of the carboxylate butyrylcholinesterase complexes observed in crystal structures of human butyrylcholinesterases from various sources, and demonstrates the remarkable ability of cholinesterases to stabilize covalent complexes with carboxylates.
Web1. sep 2011 · The field of small-molecule crystallography, where atomic resolution data are routinely collected, achieved a high degree of automation in structure solution and refinement several decades ago [1]. As a result, the current growth rate of the Cambridge Structural Database (CCSD) [2] is more than 15,000 new structures per year.

It should be noted that the overall B-factor can change by ± a constant.
Web1.5 Least-squares refinement Small molecules are usually refined by full-matrix methods (using the L.S. instruction), which give the best convergence per cycle, and allows standard uncertainties to be estimated. The CPU time per cycle required for full-matrix refinement is approximately proportional to the WebAbstract. Although fluorescence microscopy provides a crucial window into the physiology of living specimens, many biological processes are too fragile, are too small, or occur too rapidly to see clearly with existing tools. We crafted ultrathin light sheets from two-dimensional optical lattices that allowed us to image three-dimensional (3D ...
