Central metabolism of purple non-sulfur bacteria (catabolic and amphibolic reactions). Reactions that are specific for Rs. rubrum (rru; red dotted lines), Rba. sphaeroides, (rsp, blue dotted lines) and Rps. palustris (rpa; green dotted line) are indicated. Reactions with dashed lines occur only in two of the three representatives (indicated by their abbreviations). Solid lines indicate reactions present in all three species.
