Fig. 1

Scheme of the metabolism of R. rubrum. The main routes mentioned in this work are represented in the scheme: glycolysis, tricarboxylic acid (TCA) and Calvin–Benson–Bassham (CBB) cycles, Ethylmalonyl (ETM) and PHBV synthesis pathways. Energetic phenomena occurring in the periplasm and the inner membrane (IM), are depicted: cofactor recycling in the respiratory chain (RCh), the oxidative phosphorylation catalysed by the ATP-Synthase (AS) and the cyclic photosynthesis carried on by the photosynthetic apparatus (PA). The compounds measured in this work are highlighted in bold. Green arrows indicate NAD(P)+ regenerating reactions. G3P, glyceraldehyde-3-phosphate; 3PG, 3-phosphoglycerate; BPG, 1,3-bisphosphoglycerate; GAP, glyceraldehyde-3-phosphate; Ru5P, ribulose-5-phosphate; RuBP, ribulose-1,5-bisphosphate; RuBisCO, ribulose-1,5-bisphosphate carboxylase; PEP, phosphoenol-pyruvate
