 | | MFI measures the level of breakdown of the muscle proteins that hold the myofibrils together and it is strongly associated with indices of meat tenderness. | | | The reason for this tenderization is breakdown of proteins that are responsible for structural integrity of myofibrils. | | | A method to quantify the extent of postmortem tenderization is called the Myofibril Fragmentation Index (MFI). |

| | With a myofibril suspended between needles, leupeptin was washed out from the buffer by changing the solution six times. | | | Because there is no reason to suppose that such interactions are absent in skeletal muscle sarcomeres, we conclude that the most likely scenario is one in which passive elastic recoil is opposed by viscous forces originating in weak actin-titin associations. | | | Myofibrils were isolated from freshly excised rabbit psoas skeletal muscle as described previously (Linke et al. |

| | Assembly of thick filaments and myofibrils occurs in the absence of the myosin head |
| | The likely explanation for the myofibril assembly defects we observe is that headless myosin is deficient in its interactions with other components of the sarcomere. | | | Our results demonstrate that the myosin head is dispensable for thick filament assembly and many aspects of myofibrillogenesis, but that the interaction of the head with other myofibrillar components is likely to be required for defining the precise geometry of the sarcomere. | | | This is consistent with our earlier study demonstrating that adult and embryonic MHCs display isoform-specific properties in stabilizing myofibril structure (Wells et al., 1996). |

| | Delgado et al., August 2001 |
| | Discovery that a significant proportion of μ-calpain becomes associated with the myofibril during postmortem storage raised an attractive new explanation for the mechanism of postmortem tenderization. | | | Hence, it seems unlikely that the myofibril-bound calpain has a significant role in postmortem tenderization of ovine longissimus. | | | Over 25% of total μ-calpain was bound to myofibrils from at-death muscle, and this increased to ~40% after 1 d postmortem. |

| | LARGE MYO PICT |
| | In the nascent myofibril, the alpha-actinin-rich Z-bodies have begun to laterally associate, possibly through interaction with titin. | | | Overlapping muscle myosin II filaments bound to titin are present at this stage. | | | In the mature myofibril the alpha-actinin containing Z-bodies fuse to form the wide lateral arrays of mature Z-bands; nonmuscle myosin IIB is lost whereas muscle myosin filaments are now aligned into A-bands. |

| | Muscle is composed of muscle cells (sometimes known as "muscle fibers"). | | | Muscle cells are bound together by perimysium into bundles called fascicules; the bundles are then grouped together to form muscle, which is lined by epimysium. | | | Within the cells are myofibrils; myofibrils contain sarcomeres, which are composed of actin and myosin. |
