A phospholipid headgroup might be rotationally disordered and washed out, especially if it isn’t exactly the correct binding partner. It does look very much like lipid density to me. Attempts to model a diacyl glycerol and PEGs should be revealing.

But I see not much blue density. Presumably this fills out if you contour at a lower but still reasonable level? ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=CCP4BB&A=1
