Magnetic anisotropy of the visual pigment rhodopsin.

Abstract

A new estimate of diamagnetic anisotropy of the frog rhodopsin is reported. The estimate is obtained by combining the data of magnetic field induced orientation of isolated frog rod outer segments as measured by Chagneux and Chalazonitis (1972) and the data of diamagnetic anisotropy of lecithin membranes as recently reported by Boroske and Helfrich (1978). The anisotropy of the volume susceptibilities of frog rhodopsin is calculated to be 4.4 X 10(-8) cgs unit/cm3, which corresponds to 1.5 X 10(-27) cgs unit/molecule, or 9.0 X 10(-4) cgs unit/mol.
