On cryodenaturation of chicken myofibrillar proteins
Cryobiology, 1968Summary Myofibrillar protein preparations isolated from chicken pectoralis major containing 81 to 95% protein and 3 to 4% lipids, on dry weight basis, were used as a model system to study the nature of protein and lipid changes occurring as a result of frozen storage.

Ionic Strength and Myofibrillar Protein Solubilization
Journal of Animal Science, 1987Myofibrils from bovine longissimus muscle were obtained at 2 h postmortem and incubated in .10 to .35 M ionic strength buffers under various conditions in vitro. Increasing ionic strength or increasing the incubation time from 1 to 72 h decreased the turbidity of suspensions of myofibrils and increased myofibrillar solubilization (P less than .01 for ...

Interaction of Fish Myoglobin and Myofibrillar Proteins
Journal of Food Science, 2008ABSTRACT: Interactions between fish myoglobin (Mb) and myofibrillar proteins were investigated in a Mb‐natural actomyosin (NAM) model at 4 °C. Increases in metmyoglobin (MetMb) formation and the relative content of bound Mb were observed, as were decreases in whiteness and Ca 2+

Myofibrillar Proteins of Skeletal Muscle
1971Publisher Summary Muscle is a highly integrated chemical machine. One of the most impressive aspects of this integration is the ability to increase the rate of energy utilization by approximately 2500-fold within milliseconds. This efficient transduction of chemical into mechanical energy occurs through the subtleties of the interactions of myosin ...

The effect of acidification on myofibrillar proteins
Meat Science, 1994Isolated myofibrillar proteins of mutton, beef and chicken were treated with an acidulent to give various pH values and stored at 5°C for 20 h before analysing the proteins using sodium dodecylsulphate polyacrylamide gel electrophoresis. It was found that protein degradation occurred below pH 4·5, with a decrease in band intensity of all major ...

Contribution of Sarcoplasmic Proteins to Myofibrillar Proteins Gelation
Journal of Food Science, 2012Abstract: Surimi, a refined protein extract, is produced by solubilizing myofibrillar proteins during the comminuting and salting stages of manufacturing. The resulting paste gels on heating to produce kamaboko or a range of analog shellfish such as crab claw, filament sticks, fish mushroom, and so on.

The solubilization of myofibrillar proteins by calcium ions
Meat Science, 1991The effect of elevated levels (30 mm) of Ca(2+) and other divalent metals ions on rabbit psoas myofibrils was studied to determine whether these caused solubilization of structural proteins and if so whether the effect was due to salting-in or to proteolytic fragmentation resulting from activation of calpains.

Heterogeneous Turnover of Myofibrillar Protein
Nature New Biology, 1972TO investigate the heterogeneity of turnover of proteins of the myofibril, we developed “a continuous double isotope method” which is a modification of the continuous isotope administration method. The assumptions involved in the use of the double isotope method, proposed by Schmike1, are not applicable in the case of proteins of the myofibril because ...

Myofibrillar protein pattern in experimental myotonia in rats
Journal of the Neurological Sciences, 1976Experimental myotonia was induced in rats by long-term administration of 20,25-diazacholesterol. Electrophysiological, morphological and biochemical investigations were carried out on m. soleus, m. extensor digitorum longus and m. gastrocnemius. The effect of 20,25-diazacholesterol administration on myofibrillar proteins was studied and a significant ...

Dephosphorylation enhances postmortem degradation of myofibrillar proteins
Food Chemistry, 2018Protein degradation is primarily responsible for postmortem meat tenderization, which might be affected by phosphorylation. The objective of this study was to investigate the effect of phosphorylation on myofibrillar proteins degradation in muscle during postmortem. Here we modulated the phosphorylation status of protein by protein kinase inhibitor and
