Short summary
Upon the expression of fumarate reductase in E. coli we analyzed the metabolic behavior under aerobic and anaerobic conditions. Furthermore we characterize the impact on electrochemical behavior of E. coli. We show expression of fumarate reductase (frd) BioBrick BBa_1465102 using SDS-PAGE in combination with MALDI-TOF/MS. Activity could be shown with HPLC analysis.
SDS-PAGE
The fumarate reductase could be detected in purified membrane and periplasmatic protein fraction. Proteins were fractioned by cold osmotic shock of E. coli KRX at different steps after induction of protein expression. SDS-PAGE shows the expression of fumarate reductase in E. coli KRX under control of T7 promotor (BBa_K1465102). Fumarate reductase consist of four subunits, two large catalytic and two smaller membrane associated subunits. The two catalytic subunits could be detected via SDS-PAGE.
