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 ...

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 ...

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.

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.

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 ...

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+

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

Calcium-Sensitivity Modulation of Cardiac Myofibrillar Proteins
Journal of Cardiovascular Pharmacology, 1989Myocardial contractile force may be altered not only by changing intracellular free Ca2+ but also by increasing or decreasing the calcium responsiveness of the myofilaments. The latter effect may be due to interventions that decrease the calcium affinity of troponin C, such as intracellular acidosis or factors that act "downstream" of the calcium ...

Protein Ingestion Increases Myofibrillar Protein Synthesis after Concurrent Exercise
Medicine & Science in Sports & Exercise, 2015We determined the effect of protein supplementation on anabolic signaling and rates of myofibrillar and mitochondrial protein synthesis after a single bout of concurrent training.Using a randomized crossover design, eight healthy males were assigned to experimental trials consisting of resistance exercise (8 × 5 leg extension, 80% 1RM) followed by ...

High pressure effects on myofibrillar proteins
High Pressure Research, 2000Abstract Myofibrillar proteins were extracted from post rigor bovine meat with a potassium phosphate/potassium chloride buffer. Viscoelastic properties of myofibrillar properties were studied in a 0.6MKCl buffer, at pH = 6, used in an oscillating mode. Enthalpy patterns were determined with a differential scanning calorimeter.
