Protease activity units
WebbThe Collagenase Digestive Unit (CDU) assay 10,11 measures predominantly the Collagenase I activity, which cleaves two of the three helical chains in the long, undenatured collagen protein. Collagenase II activity is measured by this enzyme’s ability to cut a short synthetic peptide, N-[3-(2-Furyl)acryloyl)]-Leu-Gly-Pro-Ala (FALGPA, see … WebbProteolysis can terminate the activity of a protein--e.g., capsases mediate apoptosis, which is a vital step in the life cycle of the cell. Proteolysis contributes to defense systems too, …
