Extended Data Fig. 6: Proteomic analysis of the soluble fraction of cells in the binary culture.

Protein extraction was performed with a non-denaturing detergent. Only the 150 most abundant proteins of ‘Candidatus V. moutnovskia’ are shown. a. Binary culture grown on medium with yeast extract and sulphate as the electron acceptor. b. Binary culture grown on medium with yeast extract and elemental sulphur as the electron acceptor. Protein abundances in mol% were estimated from nemPAI values58. Data are shown as the mean of n = 2 independent experiments fitted into a model.
