A common strategy for identifying distantly relatedhomologous proteins is to search the database using a shortsignature sequence indicative of the particular proteinfunction. Why is it better to search with a short sequencethan with a long sequence? Do you not have more chancesfor a “hit” in the database with a long sequence?
