The cyanobacterial water-soluble orange carotenoid binding protein (OCP) is an ideal system for study of the effects of protein environment on photophysical properties of carotenoids. It contains a single pigment, the carotenoid 3'-hydoxyechinenone (hECN). In this study, we focus on spectroscopic properties of hECN in solution and in the OCP, aiming to elucidate the spectroscopic effects of the carotenoid-protein interaction in the context of the function(s) of the OCP. The noncovalent binding of hECN to the OCP causes a conformational change in the hECN, leading to a prolongation of the effective conjugation length. This change is responsible for shortening of the S, lifetime from 6.5 ps in solution to 3.3 ps in the OCP. The conformational...
