Abstract :

Investigation of the mutant proteins of Trp182 and 9-desmethylretinal containing bacteriorhodopsin by Fourier transform infrared and visible absorption spectroscopic methods reveals the mediation of 9-methyl group in the interaction of Trp182 with the retinal side chain. The conversion of L intermediate of bacteriorhodopsin to M intermediate is influenced by this interactions.
