NotesNotes

• 4tst is a useful PDB id for a non-existing structure *Search for this page with the word BelieveItOrNot -- all the words in the real title "Believe It Or Not!" are so common that they are ignored by the search index mechanism (see Help:Stop Words), so you will not succeed searching for the real title.
