| Research Abstract |
Cold-adaptation mechanism of Shewanella livingstonensis Ac10 was analyzed. We identified cold-inducible proteins of this bacterium and analyzed their functions. We found that PspA involved in the response to membrane stress and MreB involved in cell division are important for cold adaptation. We also found that phospholipids containing eicosapentaenoyl group interact with various membrane proteins and affect their folding and properties to maintain the function of the cell membrane at low temperatures.
