Abstract excerpt

Light-induced radicals were detected by electron paramagnetic resonance (EPR) and pulsed electron-nuclear double resonance (ENDOR) in the BLUF-domain protein TePixD of the thermophilic cyanobacterium Thermosynechococcus elongatus BP-1. The illumination of TePixD at 5-200 K derived an EPR signal with a separation of 85 G between the main peaks around g = 2, showing a typical Pake's pattern of magnetic...
