FIG 1.

Central carbon metabolism in pathogenic Acinetobacter. The gray arrow indicates that gluconolactone can be nonenzymatically hydrolyzed to gluconate and the enzyme is not typically encoded in A. baumannii and closely related species. Abbreviations: PQQH2, reduced pyrroloquinoline quinone; 6PG, 6-phosphogluconate; KDGP, 2-keto-3-deoxy-6-phosphogluconate; G6P, glucose-6-phosphate; F6P, fructose-6-phosphate; FBP, fructose-1,6-bisphosphate; E4P, erythrose-4-phosphate; S7P, sedulose-7-phosphate; X5P, xylose-5-phosphate; Ri5P, ribulose-5-phosphate; R5P, ribose-5-phosphate; G3P, glyceraldehyde-3-phosphate; DHAP, dihydroxyacetone phosphate; BPG, 1,3-bisphosphoglycerate; 3PG, 3-phosphoglycerate; 2PG, 2-phosphoglycerate; PEP, phosphoenolpyruvate; GLX, glyoxylate.
