As already posted, fuzznuc and fuzzpro accept prosite patterns.
However, as EMBOSS includes the Henry Spencer regular expression
library (both versions) it is very easy to implement simple regular
expression searches. They are complicated by ambiguity codes in the
pattern and in the sequence(s), which is why Alan's implementation
of prosite patterns is currently preferred to making modifications
to the regexp code.
If there is interest, we could very easily implement a simple regular
expression search (add regular expressions to the ACD types for the
user interface, simple loop, about 30 minutes should do it. Then a
little longer to find a catchy name :-)
... but A would not match N and N would not match A unless we put
rather more effort in ...
