title: In vitro sodium bisulfite mutagenesis of restriction endonuclease recognition sites.
abstract: Sodium bisulfite treatment of single-stranded DNA deaminates exposed cytosine residues to form uracil, resulting in cytosine-to-thymidine transition mutations following DNA replication. We have used this reaction in vitro to destroy the recognition sequences for the restriction endonucleases HindIII and XmaI in the aminoglycoside 3'-phosphotransferase I coding region of plasmid pUC4K. This procedure should be applicable to the mutation of any recognition sequence of restriction endonucleases which generate cytosine-containing single-stranded ends. The possibility of mutagenesis of restriction sites to generate stop codons in coding regions is discussed.
