The gene SSO0495 (proC), which encodes pyrroline-5-carboxylate reductase (P5CR) from the thermoacidophilic archeon Sulfolobus solfataricus P2 (Ss-P5CR), was cloned and expressed. The purified recombinant enzyme catalyzes the thioproline dehydrogenase with concomitant oxidation of NAD(P)H to NAD(P)(+). This archeal enzyme has an optimal alkaline pH in this reversible reaction and is thermostable with a half-life of approximately 30 min at 80 degrees C. At pH 9.0, the reverse activation rate is nearly 3-fold higher than at pH 7.0. The homopolymer was characterized by cross-linking and size exclusion gel filtration chromatography. Ss-P5CR was crystallized by the hanging-drop vapor-diffusion method at 37 degrees C. Diffraction data were obtained to a resolution of 3.5 angstrom and were suitable for X-ray structure determination. (C) 2008 Elsevier Inc. All rights reserved.
