Hello Eleanor
If I may ask, are you sure the pucker is correct for the proline on the left?
In my humble opinion the proline C-alpha doesn't look very tetrahedral and
maybe this residue has some unexplained density at the back. Maybe the peptide
with the odd extension wants to go down and to the left a bit. How does the
extension behave at higher contour levels and how does the difference map look
in that region? It looks quite high resolution data, so in fear of repeating
myself today, I am curious if it has been refined with anisotropic B's since
this does have a habit of cleaning-up oddities in the maps.
Beyond that I can only suggest its a Bernal bug.
Best wishes, Jon.C.

There is at least one other similar feature???
