This is a neat idea. I like to think about programming such stuff.
I can easily get to the step where I have the degenerate nucleotide
sequence, but what is the easiest way to search a restriction site
database? Is there a list of all restriction enzymes that is publicly
available? Ideally, I would guess that one recognition sequence
per line, and nothing else, would be best, with the corresponding
names in a second file in the same order. Then one could march through
the sequence, say, 5 bases at a time, and try all possible combinations
anytime there is an ambiguous character. Any search hit gets saved along
with the current position. Sounds easy, but possibly slow, if such
a listing exists.
Email me if you have such a list -- my contributions would be freeware.
And I assume that there are site-directed mutagenesis methods available
so that one can actually do this? (Sorry for my naivete'.)
