Abstract

The specificity of cleavage of Bam HI is altered in the presence of hydrophobic reagents, such as glycerol and M2SO. The enzyme with altered specificity, designated Bam HI.1, generated digestion patterns of various DNAs, which were distinct from those generated by Bam HI. Cleavage sites recognized in phiX174 RF DNA in the presence of these hydrophobic reagents are not related to the Bam HI palindrome. Bam HI.1 appears to be an endogenous form of Bam HI that can be expressed by altering the hydrophobicity of the reaction.
