meat quality. The proteolytic enzymes, the substrate it was shown that the presence of calpains, are implicated in the proteolysis oxidizing species does significantly impede Chemistry and Biochemistry of Meat 19 the ability of calpains to degrade their sub- (NOS). There are three major isoforms of strates. Oxidation with H2O2 significantly NOS: neural, inducible, and endothelial. limits proteolytic activity of μ- and m-calpain Skeletal muscle expresses all three isoforms; against the fluorescent peptide Suc-Leu- however, the neural form, nNOS, is thought Leu-Val-Tyr-AMC, regardless of the pH or to be the predominant isoform (Kaminski and ionic strength. Similar results were seen Andrade 2001). These enzymes utilize argi- when using purified myofibrils as the sub- nine as a substrate and catalyze the following
