Pathway Description
D-Arabinose Degradation I
Escherichia coli
Metabolic Pathway
Wild-Type E.coli K-12 can not directly use D-arabinose as a sole source of carbon and energy; hence, E.coli uses the enzymes of the fucose degradation pathway to degrade D-arabinose for further utilization. D-arabinose can be metabolized to form dihydroxy-acetone phosphate for entering the central metabolism. Glycolaldehyde can be further catalyzed to form glycolic acid by lactaldehyde dehydrogenase.
