Solid-State Photo-CIDNP Effect Observed in Phototropin LOV1-C57S by ¹³C Magic-Angle Spinning NMR Spectroscopy

Abstract

Until now, the solid-state photo-CIDNP effect, discovered in 1994 by Zysmilich and McDermott, has been observed selectively in photosynthetic systems. Here we present the first observation of this effect in a nonphotosynthetic system, the blue-light photoreceptor phototropin LOV1-C57S using (13)C magic-angle spinning (MAS) NMR.
