Distribution of dipeptidyl aminopeptidase IV (dipeptidyl hydrolase, EC 3.4.14.5) was examined in the plasma, kidney, liver, ordinary muscle, dark muscle, and brain, of 4 species of cultured fishes, carp Cyprinus carpio, eel Anguilla japonica, tilapia Sarotherodon niloticus, and yellowtail Seriola quinqueradiata, using glycyl-L-prolyl p-nitroaniline as substrate. In all these fishes, the kidney (13.9-39.8U/g) showed the highest enzyme activity, followed by the liver (9.65-26.1U/g), brain (1.95-7.65U/g), dark muscle (0.99-2.53U/g), and ordinary muscle (0.34-1.49U/g). The activities of fish plasma were 4.16-14.6U/l. The activity levels of piscine tissues were, as a whole, much lower than those in the corresponding tissues of the rat analyzed as a control. The activity level of piscine plasma were also clearly lower than in mammalian serum.
