BIOPHYSICS. For the article “Cytochrome c folding pathway: Kinetic native-state hydrogen exchange,” by Linh Hoang, Sabrina Bédard, Mallela M. G. Krishna, Yan Lin, and S. Walter Englander, which appeared in number 19, September 17, 2002, of Proc. Natl. Acad. Sci. USA (99, 12173–12178; First Published August 26, 2002; 10.1073/pnas.152439199), the authors note that the text did not adequately credit prior works that have used EX1 hydrogen exchange (HX) methods to measure protein or nucleic acid opening rates in various ways, even if not in the context of folding pathways. Most analogous are the works cited in refs. 24 and 25 of our paper (refs. 1 and 2 below) and a more recent simultaneous work on the folding of OspA (3).
