An outline of key phosphorus metabolic processes. a Two-component system, oxidative phosphorylation, transporters, and organic phosphoester hydrolysis. b Pyruvate metabolism, phosphonate and phosphinate metabolism, phosphotransferase system (PTS), pentose phosphate pathway, purine metabolism, and pyrimidine metabolism. X may be O, F, C, or S; R is any alkyl group. PEP, phosphoenolpyruvate; PGA, including 2-phosphoglycerate and 3-phosphoglycerate; PRPP, α-D-ribose-1-diphosphate-5P; GAR, 5′-phosphoribosylglycinamide; FGAR, 5′-phosphoribosyl-N-formylglycinamide; FGAM, 2-(formamido)-N1-(5′-phosphoribosyl) acetamidine; AIR, aminiimidazole ribotide; CAIR, 1-(5′-phospho-D-ribosyl)-5-amino-4-imidazolecarboxylate; N5-CAIR, 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole; SAICAR, 1-(5′-phospho-D-ribosyl)-5-amino-4-(N-succinocarboxamide)-imidazole; AICAR, 1-(5′-phosphoribosyl)-5-amino-4-imidazolecarboxamide; FAICAR, 1-(5′-phosphoribosyl)-5-formamido-4-imidazolecarboxamide
