Thermal regulation of fatty acid synthetase from Brevibacterium ammoniagenes. 1979

A Kawaguchi, and Y Seyama, and K Sasaki, and S Okuda, and T Yamakawa

The fatty acid composition of Brevibacterium ammoniagenes was affected by the temperature of growth. As the growth temperature was lowered, the proportion of unsaturated fatty acids increased. The fatty acid synthetase obtained from B. ammoniagense produced oleic acid as well as saturated fatty acids. The ratio of unsaturated to saturated fatty acids synthesized by this enzyme in vitro was dependent on the temperature of the enzyme reaction but not on the growth temperature of B. ammoniagenes from which the enzyme was prepared. These results suggest that the changes of composition in cellular fatty acids reflect the temperature dependence of the fatty acid synthetase.
