The recent discovery of marine biodiversity shows that a large part of the biosphere is a high-pressure environment. The existence of a specific pressure adaptation is still an open question. Recently, the first obligate piezophilic hyperthermophilic microorganism was isolated from hydrothermal vent. This finding suggests the existence of a specific enzyme adaptation with respect to high pressure.To deeper understanding protein adaptation with respect to high pressure, we examine the enzymatic properties of two family enzymes, malate deshydrogenases and glyoxylate hydroxypyruvate reductases arising from piezophilic and non-piezophilic organisms.Using an integrated approach combining enzymology, biophysics and X-ray crystallography, we revea...
