FTIR Spectroscopy of the M Photointermediate in pharaonis Phoborhodopsin [PDF]

open access: yesBiophysical Journal, 2002
pharaonis phoborhodopsin (ppR; also called pharaonis sensory rhodopsin II, psR-II) is a photoreceptor for negative phototaxis in Natronobacterium pharaonis. During the photocycle of ppR, the Schiff base of the retinal chromophore is deprotonated upon formation of the M intermediate (ppR(M)).
