| Abstract |
To investigate a possible chromosomal clustering of glycolytic enzyme genes, the complete nucleotide sequence of the 8029 bp insert of Escherichia coli DNA in the ColE1 plasmid pLC33-5 of the Clarke and Carbon collection (Clark and Carbon, 1976) was determined. Genes (pgk, fda) encoding the phosphoglycerate kinase and Class II fructose 1,6-bisphosphate aldolase, respectively, of E. coli were identified. The phosphoglycerate kinase was found to be highly homologous in primary structure to the same enzyme from eukaryotic organisms. A further large open reading frame, designated gapB, was also identified, which on the basis of sequence homology, appears to encode another glycolytic enzyme, glyceraldehyde 3-phosphate dehydrogenase. This putative gene differs significantly from that (designated gapA) already identified as coding for this enzyme in E. coli and which maps elsewhere on the chromosome. The products, if any, of several other open reading frames remain to be identified. |
