Primary structure of the chromosomal origins (oriC) of Enterobacter aerogenes and Klebsiella pneumoniae: comparisons and evolutionary relationships.
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.
