Show Summary Details


The 569,750 base pair sequence corresponding to the 28.0–40.1 min region on the genetic map of Escherichia coli K-12 (W3110) was determined. This region includes the replication terminus region and contained at least 549 potential open reading frames. Among them, 160 (29%) were previously reported, 174 (32%) were homologous to other known genes, 102 (18%) were identical or similar to hypothetical genes registered in databases, and the remaining 113 (21%) did not show a significant similarity to any other gene. Of interest was the finding of a large number of genes and gene clusters in andnear the replication termination region which had been thought to be genetically silent. Those includeda cluster of genes for fatty acid β-oxidation, the third copy of the pot (spermidine/putrescine transport system) gene cluster, the second dpp (dipeptide transport system) operon, the second dsm (anaerobic dimethyl sulfoxide reductase) operon, a cluster of fim (fimbrial) genes anda DNA helicase-like gene with a high molecular weight. In addition, we found the dnaC- and dnaT-like genes in the cryptic prophage, Rac, anda number of genes originated probably from plasmids.
