"Control of Membrane Lipid Fluidity in Bacteria"

Presented by Diego de Mendoza, Institute of Molecular and Cell Biology of Rosario, CONICET - University of Rosario, Argentina

Friday, September 22, 2006, 11:00 am — John Dunn Seminar Room, Bldg. 463

Bacteria and most poikilothermic organisms have to remodel the membrane lipid composition to survive at low temperatures. In general, these organisms respond to a decrease in growth temperature by increasing the synthesis of unsaturated fatty acids (UFAs). In this lecture I will summarize the basic features of temperature regulation of UFAs synthesis in Escherichia coli and Bacillus subtilis, in which the proposed mechanisms are firmly based on both, biochemical and genetic evidence.
