Abstract

Fresh bovine rod outer segment (ROS) preparations exhibit relatively high Mg-ATPase activity (initial rate: 400 nmole ATP hydrolysed min−1 mg rhodopsin−1). The enzyme activity is accompanied by a dramatic change in light-scattering from the ROS: in 5 min the total light-scattering decreases by about 50%. The angular dependence of this dark light-scattering increment suggests that the underlying event is a change in refractive index.
