Figure 8From: The outer membrane protein Omp35 affects the reduction of Fe(III), nitrate, and fumarate by Shewanella oneidensis MR-1The effect of proteinase K on MR-1 proteins OmcA, fumarate reductase (FR), and Omp35. Either fumarate-grown whole cells (WC) or purified outer membrane (OM) fractions isolated from fumarate-grown MR-1 were treated with proteinase K. Results of duplicate experiments are expressed as the ratio of band intensity with proteinase K vs. protease-free control. *, statistically significant from FR control to P ≤ 0.006.Back to article page
