Two-Step Structural Changes in Orange Carotenoid Protein Photoactivation Revealed by Time Resolved FTIR Spectroscopy
Published: Jan 1, 2019
Abstract
The Orange Carotenoid Protein (OCP), which is essential in cyanobacterial photoprotection, is the first photoactive protein containing a carotenoid as an active chromophore. Static and time-resolved FTIR difference spectroscopy under continuous illumination at different temperatures was applied to investigate its photoactivation mechanism. Here we demonstrate that in the OCP, the photo-induced conformational change involves at least two...
