Protein Structure Determination by Racemic and Quasi‐Racemic X‐Ray Crystallography

ChemBioChem, Volume 27, Issue 4, 25 February 2026.
Racemic mixtures of protein enantiomers facilitate formation of diffraction‐quality crystals in centrosymmetric space groups that have quantized phases which simplify structure solution. Quasi‐racemic mixtures of a protein and its mirror image isomorph similarly facilitate formation of highly ordered crystals.

Fleas

, 2008
Fleas transmit disease and parasitic worms, and cause allergic dermatitis to humans and animals. There are about 2,000 different flea species in the world and at least 325 species in North America, all belonging to the order Siphonaptera. Fleas are not likely to be confused with other insects because adults are flattened dorsal-ventrally, or side-to ...
