The predicted metabolic pathways of B. polyvacuolum. See Supplementary Table S4 for the full protein names. Proteins involved in different pathways are represented by different colors: yellow, glycolysis; pink, tricarboxylic acid (TCA) cycle; grey, electron transport chain (ETC); light-blue, amino acid metabolism; orange, pyruvate metabolism; dark-blue, fatty acid metabolism; green, iron–sulfur cluster (ISC) biosynthesis; purple, superoxide catalytic reaction; brown, other. The white shapes indicate that the protein is absent and the outlined circles indicate that some subunits of the protein have not been identified
