looking for a software comparing restriction map of a unknown cDNA with that of genes oin databases

[Niu Haoru]

Dear:
  
   I am cloning a gene,I want to eliminate  known genes  by enzyme
cleavage.

   Does anyone know of a software or a database with which I can 
compare the restriction map of the cDNA on hand with that of the genes
in cDNA databases?

   Thanks in advance.
