torsion angle dynamics, simulated annealing | The authors state that two protons (TYR516 hydroxyl, CYS 547 backbone amide) are clashing in 1 model of the 20, and are close in 6/20. While we have not been able to directly assign the chemical shifts of that hydroxyl proton given the difficulties of exchange at this site, we believe that our existing NMR data are consistent with arrangement indicating a likely H-bond between the CYS 547 amide proton and TYR 516 hydroxyl oxygen. | NMRView |
