The Ca2+ -activated neutral protease can proteolyze both Ca2+ -dependent cyclic nucleotide phosphodiesterase and smooth muscle myosin light chain kinase. Ca2+ -dependent cyclic nucleotide phosphodiesterase from rat brain was converted to the Ca2+ -independent active form by Ca2+ -activated protease. The proteolytic effects on myosin light chain kinase of Ca2+-activated protease differed in the presence and absence of the Ca2+-calmodulin (CaM) complex. In the presence of bound CaM, myosin light chain kinase (130k dalton) was degradated to a major fragment of 62 kDa, which had Ca2+/CaM-dependent enzyme and CaM-binding activity. When digestion occurred in the absence of bound CaM, myosin light chain kinase cleaved to a fragment of 60 kDa. This peptide had no enzymatic activity in the presence or absence of the Ca2+-CaM complex. Available evidence suggests that the Ca2+-activated proteases may recognize the conformational change of smooth muscle myosin light chain kinase induced by Ca2+-CaM complex.
