| Abstract: | Calcium-activated neutral proteases (CANPs) with high sensitivity (microCANP) and low sensitivity (mCANP) to calcium ions were purified individually from rabbit skeletal muscle and rabbit lung and compared as to their electrophoretic properties, calcium requirements and peptide mapping of fragments produced by S. aureus V8 protease digestion of separated subunits. All of the results suggested that there is no difference between the microCANPs as well as between the mCANPs obtained from the two tissues, with respect to the chemical and enzymatic properties. However, the contents of CANPs in these tissues were different. |
