Dear Neha,
the question depend on which residue is missing??
Is the residue is from middle or from end that is important.
If end residue is missing then no issue. but middle residue is problematic.
you can model the protein and then align it with pymol align command or any
other visualizing software.
With beat regards,
Rama david.
