Myofibrillar ATPase activity in the carp Cyprinus carpio: interactions between starvation and environmental temperature.
The myofibrillar ATPase activity of the epaxial white muscle was measured in carp Cyprinus carpio L. acclimated to 10 degrees C or 28 degrees C. As previously reported, cold acclimation was associated with an increase in the ATPase specific activity and a decrease in the thermostability. The water content of the white muscle was significantly higher in cold-acclimated fish than in warm-acclimat...
متن کاملDenaturation of myofibrillar proteins from chickens as affected by pH, temperature, and adenosine triphosphate concentration.
The susceptibility to denaturation of myofibrillar protein from chicken muscles was investigated and compared with denaturation of myofibrillar protein from pork. Immediately postmortem, the Pectoralis profundus (white muscle) and the Pubo-ishio femorale (red muscle) of six Arbor Acres chickens were collected. The Semimembranosus (white muscle) and Psoas major (red muscle) of three Yorkshire x ...
متن کاملA 2D-IR study of heat- and [(13)C]urea-induced denaturation of sarcoplasmic reticulum Ca(2+)-ATPase.
Two-dimensional infrared correlation spectroscopy (2D-IR) was applied to the study of urea- and heat-induced unfolding denaturation of sarcoplasmic reticulum Ca(2+)-ATPase (SR ATPase). Urea at 2-3 M causes reversible loss of SR ATPase activity, while higher concentrations induce irreversible denaturation. Heat-induced denaturation is a non-two-state process, with an "intermediate state" (at t a...
متن کاملChanges of carp FoF1-ATPase in association with temperature acclimation.
Previously we have shown, using two-dimensional electrophoresis, that mitochondrial ATP synthase (F(o)F(1)-ATPase) beta-subunit is the 55-kDa protein increased in cold-acclimated carp Cyprinus carpio (Kikuchi K, Itoi S, and Watabe S. Fisheries Sci 65: 629-636, 1999). To clarify the coordinate expression in various subunits of carp F(o)F(1)-ATPase with temperature acclimation, we examined the di...
متن کاملLithium-induced inhibition of Na-K ATPase and Ca ATPase activities in rat brain synaptosome.
To explore the action mechanism of lithium in the brain, the author investigated the effects of lithium on Na-K ATPase and Ca ATPase in rat brain synaptosomes prepared from forebrains by the method of Booth and Clark. The activities of Na-K ATPase and Ca ATPase were assayed by the level of inorganic phosphate liberated from the hydrolysis of ATP. Lithium at the optimum therapeutic concentration...
