The water soluble proteins extracted from the liver or the hepatopancreas of mackerel, horse-mackerel, mejina, flatfish and carp was fractionated with a DEAE cellulose column. The histamine-decomposing and -producing enzyme activites of these fractions were determined. The histamine-decomposing enzyme activity was found in 3 fractions in mackerel; in the other marine fish 2 fractions exhibited the activity. In the carp, only one was present and its activity was extremely low. The histamine-producing enzyme activity was found in 2 fractions in mackerel; in the other fish except flatfish there was only 1 fraction in every sample; no activity was found in flatfish. In mackerel there is apparently a pathway in which imidazole acetate is produced from histamine by catalysis with histaminase.
