Any chance that it is myristate or some other fatty acid?
Good luck-

Hello,
sorry for my off topic question.
I found a PEG molecule bound to the active site of my enzyme structure. And I
did not expected it there, though I used PEG as precipitant in the
crystallization condition. Now I'm wondering how could bind PEG with its
hydrophobic nature at all in the hydrophobic active site? It seems that the PEG
molecule interacts predominantly with Tryptophans (distance 3.8 A). Did anybody
observe similar cases? And which kind of interaction should there be active? I
would be grateful for your help,
cheers,
Marek
