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. Enflurane 17-26 rhodopsin Bos taurus 90-99 8392355-6 1993 These results are all consistent with a reduction of the membrane order accompanied by lateral aggregation of rhodopsin in the presence of enflurane. Enflurane 139-148 rhodopsin Bos taurus 110-119 8392355-7 1993 By comparison with the perturbation probed by a spin label, the large molecular environment change experienced by the rhodopsin molecule suggests that enflurane may concentrate at the lipid-protein interface. Enflurane 151-160 rhodopsin Bos taurus 118-127
