Crystal structure of heliorhodopsin

Nature, 2019
Heliorhodopsins (HeRs) are a family of rhodopsins that was recently discovered using functional metagenomics1. They are widely present in bacteria, archaea, algae and algal viruses2,3. Although HeRs have seven predicted transmembrane helices and an all-trans retinal chromophore as in the type-1 (microbial) rhodopsin, they display less than 15% sequence

Crystal Structure and Prediction

Annual Review of Physical Chemistry, 2015
The notion of structure is central to the subject of chemistry. This review traces the development of the idea of crystal structure since the time when a crystal structure could be determined from a three-dimensional diffraction pattern and assesses the feasibility of computationally predicting an unknown crystal structure of a given molecule.

The crystal structure of triacetylsphingosine

Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1969
The crystal structure of triacetylsphingosine (D-erythro-l,3-diacetoxy-2-acetamido-4-trans-octadecene, C24H43OsN) has been determined by direct methods. The crystals are orthorhombic, P212121, with a = 5.002, b = 8"709 and c = 60.62/~. Positional and isotropic thermal parameters of the non-hydrogen atoms were refined to give a final R index of 0"109 ...

The crystal structure of myxin

Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1968
A crystal-structure analysis of the antibiotic myxin has been carried out at -160°C. The crystal is monoclinic, P21/a, with a=t5"08, b=29.36, c=4"87 A, /~=99.9 °, Z=8, formula Cx3H10N204. The structure was determined entirely by the symbolic addition method. Ultimate refinement was by block-diagonal least-squares to an R index of 0.052. Myxin was found

Crystals and crystal structures

2015
Abstract This first chapter considers the nature of the crystalline state by constructing crystal structures. It then moves on to look at interstitial, covalent and ionic structures, stacking faults, and twins. It also looks at the crystal chemistry of inorganic compounds, coordination polyhedra, erovskites, tetrahedral, and octahedral ...
