The cGMP-phosphodiesterase and its contribution to sensitivity regulation in retinal rods

We have used the truncated outer segment preparation to measure rod cGMP-phosphodiesterase activity, as well as its modulation by Ca2+, in darkness and in light. The basal enzyme activity in darkness was approximately 0-3 s-1, and was largely independent of Ca2+ concentration from 10 nM to 10 microM...
