[Protein-crystallography] Lipase substrate analogue

[Clement Angkawidjaja]

Hi, I am working on a project for the crystallization of a bacterial lipase. 
I got some good crystals on the native enzyme, and I also want to 
crystallize the enzyme in complex with a substrate analogue (inhibitor). I 
used the commercially-available paraoxon (also called E600), but no 
inhibition occured. Does anyone know any company that sells lipase substrate 
analogue such as fatty-acid conjugated phophonates? Any suggestion will be 
highly appreciated. Thank you.
