Fan X, Gao X, Zhou C. l-arginine and l-lysine supplementation to NaCl tenderizes porcine meat by promoting myosin extraction and actomyosin dissociation. Food Chem 2024; 446:138809. [PMID: 38402768 DOI: 10.1016/j.foodchem.2024.138809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/04/2024] [Accepted: 02/18/2024] [Indexed: 02/27/2024]
Abstract
This study investigated the individual and combined effects of l-arginine, l-lysine, and NaCl on the ultrastructure of porcine myofibrils to uncover the mechanism underlying meat tenderization. Arg or Lys alone shortened A-bands and damaged M-lines, while NaCl alone destroyed M- and Z-lines. Overall, Arg and Lys cooperated with NaCl to destroy the myofibrillar ultrastructure. Moreover, these two amino acids conjoined with NaCl to increase myosin solubility, actin band intensity, and the protein concentration of the actomyosin supernatant. However, they decreased the turbidity and particle size of both myosin and actomyosin solutions, and the remaining activities of Ca2+- and Mg2+-ATPase. The current results revealed that Arg/Lys combined with NaCl to extract myosin and dissociate actomyosin, thereby aggravating the destruction of the myofibrillar ultrastructure. The present results provide a good explanation for the previous phenomenon that Arg and Lys cooperated with NaCl to improve meat tenderness.

Abstract
The myosin superfamily is a group of molecular motors. Autoimmune diseases are characterized by dysregulation or deficiency of the immune tolerance mechanism, resulting in an immune response to the human body itself. The link between myosin and autoimmune diseases is much more complex than scientists had hoped. Myosin itself immunization can induce experimental autoimmune diseases of animals, and myosins were abnormally expressed in a number of autoimmune diseases. Additionally, myosin takes part in the pathological process of multiple sclerosis, Alzheimer's disease, Parkinson's disease, autoimmune myocarditis, myositis, hemopathy, inclusion body diseases, etc. However, research on myosin and its involvement in the occurrence and development of diseases is still in its infancy, and the underlying pathological mechanisms are not well understood. We can reasonably predict that myosin might play a role in new treatments of autoimmune diseases.

Abstract
The present study attempted to investigate the interactive roles of protein oxidation (0-20 mM H2O2) and tetrasodium pyrophosphate (TSPP) on the crosslinking efficiency of actomyosin mediated by transglutaminase (TGase). Oxidation at 0-20 mM H2O2 was not conducive to TGase-mediated crosslinking as indicated by the relative reduction of free amine consumption from 35.3% to 11.7%, and caused the principle crosslinking sites to progressively convert from myosin subfragment-1 (S1) to subfragment-1 (S2) as evidenced by electrophoresis. However, the binding of TSPP to myosin alleviated oxidation suppression to TGase-catalyzed crosslinking in varying degrees and retarded the migration of crosslinking site from S1 to S2. Moreover, oxidation (especially 20 mM H2O2) decreased the final (90 °C) elasticity index (EI) and water holding capacity of TGase-treated actomyosin gel, while TSPP intensified those of TGase-catalyzed actomyosin gel, indicating that TSPP had a positive effect on ameliorating the oxidative stress to TGase-catalyzed gelation of actomyosin.

Abstract
This work investigated the effects of L-arginine (Arg) and L-lysine (Lys) on the tenderness of chicken breast and explored the possible mechanisms underlying this effect for the first time. The results showed that both Arg and Lys decreased the shear force and increased the pH value, sarcomere length and myofibrillar fragmentation index as well as degraded the troponin-T by keeping calpain activity in chicken breast. In addition, Arg effectively reduced Ca2+/Mg2+-ATPase activities and promoted actomyosin dissociation. These results indicated that both Arg and Lys could enhance the tenderness of chicken breast, and it could also explain why Arg was more effective than Lys in improving the tenderness of chicken breast. These results will help facilitate the development of industrial-scale methods for improving the tenderness of meat products.

Effects of l-lysine on thermal gelation properties of chicken breast actomyosin. Food Sci Biotechnol 2017; 26:549-556.

Abstract
The effects of l-lysine (l-Lys) on the water holding capacity (WHC) and texture of actomyosin (AM) gel and the possible mechanisms were investigated. l-Lys increased the WHC and hardness of the AM gel. These effects may be related to the even and continuous microstructure of the gel according to the scanning electron microscopy analysis. Furthermore, l-Lys increased the surface hydrophobic residues and the reactive sulfhydryl groups. l-Lys decreased the storage modulus at the first transition temperature but increased it at the second transition temperature and the third transition enthalpy. These results suggested that l-Lys varied the thermal behaviors and the microstructure of the AM gel by increasing the surface hydrophobicity and reactive sulfhydryl groups, ultimately contributing to the increased WHC and hardness. The changes in pH did not fully explain the results from the present study. The results were useful for understanding previous findings and may serve as a reference for the preparation of reduced-sodium and phosphate-free meat products.

Abstract
Porcine longissimus myofibrils were exposed to a hydroxyl radical-oxidizing system (10 microM FeCl3, 100 microM ascorbic acid, 1 mM H2O2) at pH 6.2 for 1-12 h. Chemical analyses (sulfhydryls, disulfide bonds, carbonyls) indicated mild protein oxidation along with almost 40% loss of protein extractability in low-ionic-strength brines (<or=0.4 M NaCl, 10 mM pyrophosphate, pH 6.2). Upon graded brine irrigation (0.2-->0.6 M NaCl) with pyrophosphate, the swelling of myofibrils and the dissolution of the A-band of oxidized myofibrils were less pronounced than those of nonoxidized. This restriction of myofibril swelling, caused largely by disulfide cross-linkages formed between oxidized myosin tails, was positioned on the transversely expansible thick filaments, reflecting a significant role and susceptibility of intra- as well as intermyofilamental structures.
