additional information | Bos taurus | because the calcium concentration in postmortem muscle is high enough to activate mu-calpain, but not m-calpain, it seems reasonable to conclude that mu-calpain is responsible for postmortem degradation of calpastatin. Degradation of calpastatin by mu-calpain reduces calpain-inhibitory activity and is probably an important event in regulation of postmortem proteolysis, and, thus, meat tenderness | ? | - |
