It is well possible, that this residue adopts different conformations in the various molecules of the asymmetric, so that in reality the reported clashes are avoided. The high B values and the weak visible electron density prevent a clear observation in this regard. We, therefore, chose to refine a conformation that is most consistent with the visible density and conforms with stereochemical requirements. It is also worth mentioning that, for the second molecule of this homodimer (CHAIN A), this region shows much stronger electron density. The structural model of CHAIN A, therefore, gives a very clear, and much better, description of this region. Consistently, we show in our publication a symmetry operated homodimer consisting of two CHAIN A models.
