RESUMO

The nucleotide sequences of the Enterobacter aerogenes and Klebsiella pneumoniae DNA replication origins (oriC) were determined and compared with those of Escherichia coli and Salmonella typhimurium. Four interrelated, 9-base-pair repeats were identified from the conserved regions within the minimal origin. Evolutionary rates calculated from the minimal origin sequences yielded a quantitative phylogenic tree which agreed with the taxonomic classification of these genera.
