WebFind the list of rotamer outliers, and click on Leu 27 from the A chain, which will center on this residue in the Coot window. As you can see in Coot, this orientation is not a terrible fit to the density - but it is a rotamer outlier and energetically unfavorable due to an eclipsed Chi angle, and it has a suggestive difference peak. In chemistry, conformational isomerism is a form of stereoisomerism in which the isomers can be interconverted just by rotations about formally single bonds (refer to figure on single bond rotation). While any two arrangements of atoms in a molecule that differ by rotation about single bonds can be referred to as different conformations, conformations that correspond to local minima on the potential energy surface are specifically called conformational isomers or confor…
