Fig. 5.

Comparative proteomics of proteins possibly involved in pyruvate fermentation of S. multivorans and S. cavolei. Comparison of cells grown with pyruvate alone was done with cells grown with pyruvate/fumarate. For quantified proteins the protein intensity ratio is given as colored squares. Nonsignificantly altered proteins levels are marked with an equal sign (p values > 0.05). Proteins exclusively found in pyruvate-fermenting cells are colored dark gray. All data were obtained from three independent biological replicates. Hyf-like Hyf hydrogenase (SMUL_2383–2392; SCA02S_RS01920-RS01965), MBH membrane-bound hydrogenase (SMUL_1423–1425; SCA02S_RS01350-RS01360), Fd ferredoxin (SMUL_0303; SCA025_RS12260), PFOR pyruvate:ferredoxin oxidoreductase (SMUL_2630; SCA02S_RS04525), Pyr pyruvate, Fum fumarate
