We have cloned from Pseudomonas putida a gene homologous to Escherichia coli dnaA, and determined the sequence of the gene and its neighboring region. The dnaA gene and at least three other genes, dnaN, recF and gyrB, were found to be highly homologous to the genes in the dnaA regions of the E. coli and Bacillus subtilis chromosomes. A non-translatable region of some 600 bp immediately upstream of the dnaA gene is also conserved in the three bacteria and contains 3, 12, and 14 DnaA-boxes (TTATCCACA and closely related sequences) in E. coli, P. putida and B. subtilis, respectively. The present results confirm our hypothesis that the dnaA region is the replication origin region of the ancestral bacterium and that the essential feature of the dnaA and DnaA-box combination is conserved in most eubacteria and plays a central role in initiation of chromosomal replication.
