Liver 3-hydroxyanthranilic acid oxygenase activity in rainbow trout (Oncorhynchus mykiss).
1. In rainbow trout, 3HAA activity was comparable with those of terrestrial animals; 3HAA:PC activity ratio suggests ineffective conversion of tryptophan to niacin. 2. Inactivation as well as reactivation under different conditions was investigated. 3. Some characteristics of the enzyme extract were studied with the aim of optimizing assay in fish.
