Here, we build upon the existing BLUES framework by introducing a new move type, wherein selected sidechains are rotated by way of NCMC move proposals. Given a list of residue indices, BLUES identifies all significant rotatable bonds within the selected sidechains, where a significant rotatable bond is here defined to mean a rotatable bond for a torsion for which neither terminal atom is a hydrogen. For each NCMC move proposal, one of these bonds is randomly selected and rotated after scaling off interactions between the downstream atoms and the surrounding environment. During this process, the work done during the NCMC move proposal is tracked and the move is either accepted or rejected accordingly using the Metropolis accep-tance criterion.
