Abstract excerpt
We previously found that the enzymatic activity of 3-isopropylmalate dehydrogenase from the obligatory piezophilic bacterium Shewanella benthica strain DB21MT-2 (SbIPMDH) was pressure-tolerant up to 100 MPa, but that from its atmospheric congener S. oneidensis strain MR-1 (SoIPMDH) was pressure-sensitive. Such characteristics were determined by only one amino acid residue at position 266, serine (SoIPMDH) or...
