Exercise: patmatmotifs

unix % patmatmotifs
Search a motif database with a protein sequence
Input sequence: xlrhodop.pep

In our case we already know that our sequence is a rhodopsin. However, if you had an unknown sequence, we hope you can see that identifying motifs might provide you with information to help you plan further experiments.
