Abstract:
A thermostable thioredoxin reductase isolated from Sulfolobus solfataricus (SsTrxR) has been successfully crystallized in the absence and in the presence of NADP. Two different crystal forms have been obtained. Crystals of the form that yields higher resolution data (1.8 A) belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 76.77, b = 120.68, c = 126.85 A. The structure of the enzyme has been solved by MAD methods using the anomalous signal from the Se atoms of selenomethionine-labelled SsTrxR.
