The authors stated that "The crystals used in the reported study¹¹ of beSOD were obtained from a sample of protein which had reacted with 10 mol equiv of cisplatin for 2 weeks (under unspecified conditions)." For clarification the authors modify the final phrase so that it reads "under unspecified conditions of light exposure".

The chemical conditions of crystallisation are clearly stated in ref. 11. In view of the differences in platinated forms of the protein found in crystals and in solution, it is interesting to consider whether exposure to light could have influenced the course of the reactions during the experiments on crystals.
