Bioperl: Checking DNA alphabeth

I am writing a script to process some DNA sequences which are in fasta format. 
Now I would like to check if these sequences contain other symbols then ACGT,
like N or degenerate symbols. 
Is there a function in bioperl that does this or has someone any idea which
regular expression to use?

Thanks,
Gert Thijs
