2 Most biological photoreceptors can be described as light-activated switches, which thermally recover to the dark-adapted state. John T. M. Kennis, and Tilo Mathes Interface Focus 2013;3:20130005 ©2013 by The Royal Society

3 (a) BLUF domain of Slr1694 in dark- and light-adapted states illustrating the putative glutamine rotation mechanism. John T. M. Kennis, and Tilo Mathes Interface Focus 2013;3:20130005 ©2013 by The Royal Society

4 Photocycle of BLUF domains as observed by ultrafast vis/IR and fluorescence spectroscopy on Slr1694. John T. M. Kennis, and Tilo Mathes Interface Focus 2013;3:20130005 ©2013 by The Royal Society

5 (a) The hydrogen bond network between tyrosine, glutamine and the flavin determines light- induced proton-coupled electron transfer. John T. M. Kennis, and Tilo Mathes Interface Focus 2013;3:20130005 ©2013 by The Royal Society

6 Chemically modified BLUF domains. John T. M. Kennis, and Tilo Mathes Interface Focus 2013;3:20130005 ©2013 by The Royal Society
