Hi, Barring orientation mishaps - it almost sounds like you have an ethyl rather than a methyl ester... Could it be that your compound is an ester of ethanol rather than methanol? Artem Dear ccp4 experts, I am trying to solve the structure of one esterase with its substrate. The structure

Dear TriNigo I would put waters in all the other difference density first (there are several obvious waters even in the section of map you sent with your email), without the substrate, and see if you see any more clues as to what's going on. Do you expect something to be added on the
