Descripción

General description

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 as a low molecular weight DNA to test the enzymatic activity of partially purified component from Perna viridis (Linn.)[1] It has also been used for investigating its effect on the calcium carbonate particle morphology by scanning electron microscopy studies[2]

Biochem/physiol Actions

Unique Sites: Within the gene for ampicillin resistance: Pst I, Pvu I, Sca I; Within the gene for tetracycline resistance: BamH I, BspM I, EcoR V, Nhe I, Nru I, Sal I, Sph I, Xma III; other unique sites: Aat II, Ava I, Bal I, Bsm I, BspM II, Cla I, EcoR I, Hind III, Nde I, Pvu II, Ssp I, Sty I, Tth111 I.

One of the most commonly used cloning vectors, pBR322, confers resistance to ampicillin and tetracycline. The DNA sequence of the entire plasmid has been published.

This plasmid is derived from the ColE1-type plasmid pMB1 and shares the same type of replication mechanism and controls as ColE1 and relatives.
