Studies on thermal denaturation of fish apomyoglobins using differential scanning calorimetry, circular dichroism, and fluorescence

Apomyoglobins from both fish (yellowfin tuna Thunnus albacares, bonito Katsuwonus pelamis, and yellowtail Seriola quinqueradiata) and mammals (sheep and sperm whale) exhibited a single endothermic peak, reflecting a two-state process of thermal unfolding. A native structure of fish apomyoglobins had...
