Abstract excerpt

Phoborhodopsin (pR or sensory rhodopsin II, sRII) and pharaonis phoborhodopsin (ppR or pharaonis sRII, psRII) have a unique absorption maximum (lambda(max)) compared with three other archaeal rhodopsins: lambda(max) of pR and ppR is approx. 500 nm and of others (e.g. bacteriorhodopsin, bR) is 560-590 nm. To determine the residue contributing to the opsin shift from ppR to bR, we constructed various ppR mutants,...
