Dear Nick,
I like your idea and your comments on this substance. 1,2-hexandiol
supposed to be chiral but probably it is used as a racemic mixture in
cosmetics. There is even a crystal structure in the PDB (4EUS) and an
associated 3 letter code. I´ll give it a try because it seems to fit

Dear Peer,
This reminds me of my colleague Michael Rossmann's discovery of a Pocket

underneath the "canyon" in enteroviruses. See

Hi Peer,
If I understand you correctly you are saying that you do not know what
substance may be in the density; then perhaps you only need to extend by
an extra atom to create a new kind of symmetrical molecule that will fit
the density?

Hi Peer,
Have you tried to model the hydroxyl O1 disordered at the carbonyl
position? Check the H-bonding pattern to the end groups, this might give
some clues.
Cheers,
