Abstract

Abstract The chimeric 3-isopropylmalate dehydrogenase enzymes were constructed from the deep-sea piezophilic Shewanella benthica and the shallow water Shewanella oneidensis genes. The properties of the enzymatic activities under pressure conditions indicated that the central region, which contained the active center and the dimer forming domains, was shown to be the most important region for pressure tolerance in the deep-sea enzyme.
