摘要

Three proteins from extremophilic bacteria-hypothetical monooxygenase from Deinococcus radiodurans, hypothetical nucleotidyl transferase from Thermotoga maritime, and hypothetical oxidoreductase from Exiguobacterium sibiricum -and the DJ-1 chaperone protein from Homo sapiens have been produced in Escherichia coli. The isolation and purification procedures developed for the recombinant proteins allowed us to achieve yields higher than 96%. Crystallization conditions enabling stable growth of crystals have been determined. X-ray experiments have been performed to test the quality of the crystals and the resolution achieved ranged from 1.2 to 1.8 ?.
