The catabolism pathways for D-gluconic acid and D-galactonic acid in bacteria. Enzymes: (1) D-gluconate dehydratase (2) D-galactonate dehydratase (3) 2-oxo-3-deoxy-D-gluconate aldolase (4) D-glyceraldehyde dehydrogenase (5) D-glycerate kinase (6) D-gluconate kinase (7) 6-phospho-D-gluconate dehydratase (8) 2-oxo-3-deoxy-6-phospho-D-gluconate aldolase (9) 6-phospho-D-gluconate dehydrogenase (10) 2-oxo-3-deoxy-D-galactonokinase (11) 2-oxo-3-deoxy-6-phospho-D-galactonate aldolase. Red scissors indicate genes that were deleted during metabolic engineering for the production of sugar acids.
