Proteolytic activation of Ca2+-dependent cyclic nucleotide phosphodiesterase from Escherichia coli.
Ca2+ -dependent cyclic nucleotide phosphodiesterase from Escherichia coli was activated by limited proteolysis. The proteolytically activated enzyme lost the sensitivity to Ca2+ but its kinetic properties were not altered.
