INITIAL EVENTS IN THE PHOTOCYCLE OF PHOTOACTIVE YELLOW PROTEIN

Overview

The light-induced isomerization of a double bond is the key event that, allows the conversion of light energy into a structural change in, photoactive proteins for many light-mediated biological processes, such as, vision, photosynthesis, photomorphogenesis, and photo movement. Cofactors, such as retinals, linear tetrapyrroles, and 4-hydroxy-cinnamic acid have, been selected by nature that provide the essential double bond to, transduce the light signal into a conformational change and eventually, a, physiological response. Here we report the first events after light, excitation of the latter chromophore, containing a single ethylene double, bond, in a low temperature crystallographic study of the photoactive, yellow protein. We measured experimental phases to overcome possible model, ... [(full description)]
