HindII, HindIII, and HpaI restriction fragment maps of bacteriophage lambda DNA

The site-specific restriction endonucleases isolated from Hemophilus influenzae strains Rc (HincII) and Rd (HindII + III), and Hemophilus parainfluenzae (HpaI) were used to digest bacteriophage lambda DNA into 34, 40, and 15 specific fragments, respectively. The sites cleaved by each of these enzymes were localized on the lambda physical map and the fragments resulting from these cleavages were electrophoretically identified on gels by (1) analysis of the digestion profiles of deletion and transducing derivatives of lambda; and (2) digesting individual fragments produced by one restriction endonuclease with another restriction endonuclease. This paper presents the HindII, HindIII, and HpaI restriction fragment maps for the entire lambda genome, and the data used to derive these maps for the region of the lambda genome between the attachment site (at 57.3% lambda) and the right vegetative end (100% lambda). The data for mapping the left arm of lambda may be found in the accompanying paper (Robinson and Landy, 1977).
