[Bioperl-l] nucleotide sequences from peptide id

[shalabh sharma]

Hi,
    i have thousands of peptide ids and i want their corresponding
nucleotide sequences.
Is there any way i can convert those peptide id to nucleotide ids , because
then i can use Bio::DB::Genbank to get the sequences , or is their any other
direct way to achieve this.

I would really appreciate if anyone can help me out.

Thanks
Shalabh
