title: SILMUT: a computer program for the identification of regions suitable for silent mutagenesis to introduce restriction enzyme recognition sequences.
abstract: We describe a set of IBM-compatible computer programs designed to selectively identify the potential sites for silent mutagenesis within a target DNA sequence. This program is based on a novel strategy of identifying amino acid motifs compatible with each restriction site (BioTechniques 12:382-384, 1991). The programs can be used to identify the suitability for the introduction of any 6-base nucleic acid sequences, such as restriction enzyme sites in cassette mutagenesis strategies. The Table program generates a table of multiple amino acid motifs for each restriction enzyme, obtained by translating each unique recognition sequence in all three reading frames. The Silmut program, which utilizes the features of Table, will further identify the presence of a match between any amino acid motif of each restriction enzyme and the input target sequence. Minor manipulations of the data base files will enable the individual researcher to identify the potential for introduction of any 6-base sequences by silent mutagenesis.
