Correction for “ Structural basis of photosensitivity in a bacterial light - oxygen - voltage / helix - turn - helix ( LOV - HTH ) DNA - binding protein

BIOPHYSICS AND COMPUTATIONAL BIOLOGY Correction for “Structural basis of photosensitivity in a bacterial light-oxygen-voltage/helix-turn-helix (LOV-HTH) DNA-binding protein,” by Abigail I. Nash, Reginald McNulty, Mary Elizabeth Shillito, Trevor E. Swartz, Roberto A. Bogomolni, Hartmut Luecke, and Kevin H. Gardner, which appeared in issue 23, June 7, 2011, of Proc Natl Acad Sci USA (108:9449–9454; first published May 23, 2011; 10.1073/pnas.1100262108). The authors note that Fig. 3 appeared incorrectly. As originally published, the color scale in Fig. 3C was inadvertently reversed (with red indicating minimal chemical shift changes and blue indicating maximal changes upon illumination). The corrected figure and its legend appear below.
