1. Four cyclic AMP phosphodiesterase-activating activities, designated as A, B, C and D, were isolated from lugworm, Arenicola cristata, by preparative flat-bed isoelectric focusing. Activators C and D were further purified by TSK 3000SW HPLC to homogeneity. 2. Activators A, B, C, and D corresponded to pIs of 4.4, 5.0, 5.2 and 5.4; their mol wts were estimated to be 36,200, 30,500, 30,200 and 28,300 respectively. 3. The protease nature of these activities were confirmed by the inhibition by several trypsin inhibitors of their activation of
phosphodiesterase
and by their hydrolysis of TAME, a synthetic trypsin substrate. Only
protease A
also hydrolyzed BTEE, a chymotrypsin substrate.
