J Magn Reson. 2000 Nov;147(1):9-16

Authors: Bertram R, Quine JR, Chapman MS, Cross TA

We describe a procedure for using orientational restraints from solid-state NMR in the atomic refinement of molecular structures. Minimization of an energy function can be performed through either (or both) least-squares minimization or molecular dynamics employing simulated annealing. The energy, or penalty, function consists of terms penalizing deviation from "ideal" parameters such as covalent bond lengths and terms penalizing deviation from orientational data. Thus, the refinement strives to produce a good fit to orientational data while maintaining good stereochemistry. The software is in the form of a module for the popular refinement package CNS and is several orders of magnitude faster than previous software for refinement with orientational data. The short computer time required for refinement removes one of the difficulties in protein structure determination with solid-state NMR.
