Figure 3.

Overview of metabolism and transport in S.thermophilum. Pathways for energy production and the metabolism of organic compounds, acids and aldehydes are shown. Transporters are grouped by substrate specificity according to their role category: amino acids/peptides/amines/purines (red), carbohydrates (yellow), cations (green), anions (pink), drugs (black) and others (blue). Arrows indicate the direction of transport. Energy coupling mechanisms are also shown. PRPP, phosphoribosyl–pyrophosphate; ATP, adenosine triphosphate; ADP, adenosine diphosphate; MCP, methyl-accepting chemotaxis protein; OAA, oxalacetic acid; 2OGA, 2-oxoglutaric acid.
