  • Title: Construction of an M13 histidine-transducing phage: a single-stranded cloning vehicle with one EcoRI site.
    Author: Barnes WM.
    Journal: Gene; 1979 Feb; 5(2):127-39. PubMed ID: 376403.
    Abstract:
    In order to create a ready source of single-stranded DNA for DNA sequence determination by the dideoxy chain-termination method, the promoter-proximal part of the histidine operon, the hisOGD region of Salmonella typhimurium, was cloned onto the single-stranded phage M13. Both orientations of the his DNA were cloned to supply DNA template for sequencing of each strand. Insertion was achieved at an HaeIII site in the intergenic region (IR) of M13, and a single EcoRI site was purposely regenerated at one boundary of the his DNA insert. Infected colonies, not plaques, were selected using the hisD gene as a selective marker. The single RI site and the hisD marker for auxotrophic selection represent improvements on the wild type M13 as a single-stranded vector for cloning other DNA.
