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. On Jul 2, 2018, at 10:36 AM, Edward A. Berry

I would favour the PEG interpretations. PEG-y snakes like to nestle against hydrophobic patches, and especially to lie on the large flat indole rings of TRP side-chains (like this one does). Gerard. -- On Mon, Jul 02, 2018 at 04:01:29PM +0100, Eleanor Dodson wrote: > Looks Pegy... > > > On 2

Is it a membrane protein? Looks like a phospholipid without the phosphate. diglyceride maybe? But I see not much blue density. Presumably this fills out if you contour at a lower but still reasonable level? On 07/02/2018 06:26 AM, Christopher Horne wrote: Does anyone have any insight into this
