A 1440-bp plasmid named pAP12875 was isolated from Acetobacter pasteurianus and its nucleotide sequence determined. An open reading frame was found capable of coding for a protein that has similarity with the replication protein of pVT736-1 from Actinobacillus actinomycetemcomitans and the 32-kDa protein of phage Pf3 from Pseudomonas aeruginosa.
