Description générale
Plasmid pBR322 was one of the first multipurpose cloning vectors constructed for use in E. coli. This plasmid is derived from the ColE1-type plasmid pMB1 and shares the same type of replication mechanism and controls as ColE1 and relatives. Plasmid pBR322 confers resistance to ampicillin and tetracycline. The plasmid sequence has been published.
The plasmid has unique restriction sites within the gene for ampicillin resistance (Pst I, Pvu I, and Sca I), within the gene for tetracycline resistance (BamH I, BspM I, EcoR V, Nhe I, Nru I, Sal I, Sph I, and Xma III), and elsewhere (Aat II, Ava I, Bal I, Bsm I, BspM II, Cla I, EcoR I, Hind III, Nde I, Pvu II, Ssp I, Sty I, and Tth111 I).

Application
Plasmid pBR322 was one of the first multipurpose cloning vectors constructed for use in Escherichia coli. This plasmid and derivatives have been used for a number of purposes including cloning, selection and expression of recombinant molecules, construction of shuttle vectors and vectors for nucleotide sequencing, studies of elements involved in gene expression, as plasmid DNA standards, and as a model system for studies on prokaryotic plasmid replication.
pBR322 Plasmid DNA from E. coli RRI has been used to study about ferrous ion-induced strand breaks in the plasmid pBR322 are mediated through hydrogen peroxide.
Actions biochimiques/physiologiques
This plasmid is derived from the ColE1-type plasmid pMB1 and shares the same type of replication mechanism and controls as ColE1 and relatives.

Ferrous ion-induced generation of single and multiple strand breaks in the DNA plasmid pBR322 induces the formation of two new plasmid forms with altered electrophoretic mobility. The yield of these plasmid forms, the circular relaxed and the linear forms, depended

Transformation of Escherichia coli plays an important role in recombinant DNA technology. Most current transformation protocols require that the cells be treated to attain a particular physiological state known as "competence," and this makes transformation procedures lengthy and arduous. Here
