Location in bacteriophage lamdba DNA of cleavage sites of the site-specific endonuclease from Bacillus amyloliquefaciens H.

摘要

The sites in Escherichia coli bacteriophage lambda DNA cleaved by the site-specific endonuclease isolated from Bacillus amyloliquefaciens H (BamI) are found to be at 0.114, 0.466, 0.580, 0.713, and 0.861 lambda units. The sites were located by analysis of the products of digestion of lambda DNA and lambda-ara transducing phage DNA, and verified by double digestion with BamI and EcoRI.
