PHOTOACTIVE YELLOW PROTEIN, 1 NANOSECOND INTERMEDIATE (287K)

Overview

Photoactive yellow protein (PYP) is a member of the xanthopsin family of, eubacterial blue-light photoreceptors. On absorption of light, PYP enters, a photocycle that ultimately transduces the energy contained in a light, signal into an altered biological response. Nanosecond time-resolved x-ray, crystallography was used to determine the structure of the short-lived, red-shifted, intermediate state denoted [pR], which develops within 1, nanosecond after photoelectronic excitation of the chromophore of PYP by, absorption of light. The resulting structural model demonstrates that the, [pR] state possesses the cis conformation of the 4-hydroxyl cinnamic, thioester chromophore, and that the process of trans to cis isomerization, is accompanied by the specific formation of new hydrogen bonds ...
