Seasonal changes in the thyroid proteinase of a teleost fish, the burbot, Lota lota L.
Proteolytic activity extracted from thyroid tissue was studied over the course of a year. The pH curves of enzyme prepared from fish collected in winter and spring were basically alike and showed three peaks of activity. The thermal stabilities, Michaelis constants, and iodoacetate sensitivity sugge...
