摘要:The dnaA gene of Staphylococcus aureus has now been cloned and sequenced. The deduced amino acid sequence of Staphylococcus aureus DnaA protein is 62% and 39% identical to those of the DnaA protein from Bacillus subtilis and Escherichia coli, respectively.Expression of the dnaA gene of Staphylococcus aureus in Escherichia coli caused lethality in an oriC-dependent manner.
