Popis: Photoreceptor guanylate cyclase is highly sensitive to nanomolar calcium concentrations. This effect is mediated by a soluble regulatory protein. Guanylate cyclase and its calcium dependent modulator protein have been purified from bovine rod outer segments and identified as a 112 kDa protein and a 26 kDa protein, respectively. Estimation of the molar quantities revealed that both proteins are present in equimolar amounts.
