—Overview of reference pathways, focused on the interconnected reactions of terpenoid, lipid and tetrapyrrole biosynthesis, mitochondrial sulfur assimilation and glycine cleavage, and ribosomal proteins. Pathways are color coded and enzymes/proteins are numbered according to the supplementary table S1, Supplementary Material online. Abbreviations: ACP, acyl-carrier protein; ALA, delta-aminolevulinic acid; Chl a, chlorophyll a; DGDG, digalactosyldiacylglycerolipids; DHAP, dihydroxyacetone phosphate; GGPP, geranylgeranyl pyrophosphate; IMS, intermembrane space; MEP, methyl-d-erythritol 4-phosphate; PEP, phosphoenolpyruvate; pyr, pyruvate; SQDG, sulfoquinovosyldiacylglycerolipids; and THF, tetrahydrofolate.
