Description

Allows the mutation of nucleotides in nucleic acids. Mutation of double-stranded DNA maintains better intra-strand hydrogen bonding if base pairs are mutated together (see example below) rather than mutating each strand separately.

For RNA, the option -rna should be used.

Options

-help 
usage information
-seq [chain]index:[complementary:]sequence[=...] 
nucleotide sequence to be mutated to
-rna 
generate RNA instead of DNA

Examples

mutateNA.pl -seq A1:AT 1bna.chainA.pdb
mutate the first two nucleotides to AT in single-stranded DNA
