Sequence of the Escherichia coli K-12 edd and eda genes of the Entner-Doudoroff pathway.

A 3.5-kb DNA fragment from the Clarke and Carbon Escherichia coli genomic clone, pLC37-44, was sequenced on both strands. Part of the zwf gene, encoding glucose-6-phosphate dehydrogenase, and all of the edd and eda genes, encoding 6-phosphogluconate dehydratase and 2-keto-3-deoxy-6-phosphogluconate aldolase, respectively, of the Entner-Doudoroff pathway, were identified. These data are compared with those of Egan et al. [J. Bacteriol. 174 (1992) 4638-4646] and important differences were noted.
