Enflurane 102-111 rhodopsin Bos taurus 19-28 8392355-2 1993 At moderately low enflurane concentration, we find that, while extrinsic probes show little membrane perturbation, rhodopsin may experience large changes with respect to the native lipid-protein interactions which modulate some of its properties. Enflurane 18-27 rhodopsin Bos taurus 115-124 8392355-4 1993 As a function of enflurane concentration, there appears to be an increasing population of rhodopsin molecules for which the metarhodopsin I-->II transition is blocked, while it is accelerated in the remaining population.

Hydrogen 26-34 rhodopsin Bos taurus 83-92 21510671-8 2011 Together with the interhelical hydrogen bonds, the salt bridges between TM6 and H9 stabilize the protein conformation of squid rhodopsin and may hinder the occurrence of large conformational changes that are observed upon activation of bovine rhodopsin.

Schiff Bases 44-55 rhodopsin Bos taurus 10-19 20557105-4 2010 This suggests that activation of rhodopsin creates a specific reaction channel for hydroxylamine or loosens the chromophore binding pocket.

Hydroxylamine 164-173 rhodopsin Bos taurus 95-104 8823182-7 1996 Judging from nitroxide mobilities, the putative extension of helix E in the aqueous phase is more dynamic than that of helix F.

Adenosine Triphosphate 128-131 rhodopsin Bos taurus 0-9 8172594-2 1994 Since we have found tht the binding of rhodopsin to the alpha subunit of transducin (alpha T) increases the susceptibility of alpha T to phosphorylation by protein kinase C-beta 1, we used this phosphorylation reaction as an initial screen for peptides that mimic the actions of rhodopsin. tetrahydrothiophene 20-23 rhodopsin Bos taurus 279-288 8172594-3 1994 The results of this screen indicated that a peptide from the C-terminal tail of rhodopsin (amino acids 325-338; KNPLGDDEASTTVS-amide; designated as peptide 3) was capable of interacting with the alpha T subunit.
