Find silent restriction sites of a given peptide sequence

Enter peptide sequence corresponding to mutagenesis primer:
exclude enzymes with less than 6 bp recognition site

Standard abbreavations of degenerate nucleotides
R = G or A
Y = C or T
M = A or C
W = A or T
B = not A (C or G or T)
D = not C (A or G or T)
H = not G (A or C or T)
V = not T (A or C or G)
N = A or C or G or T
