1. Pancreatic elastase is a compact globular protein with a hydrophobic core. 2. Other useful markers of infection are seminal elastase and seminal cytokines. 3. Human pancreatic elastase 1 ( E1 ) remains undegraded during intestinal transit. 4. Cathepsin S may be considered the most potent elastase known. 5. The gene encoding neutrophil elastase , ELA2, consists of five exons. 6. Hence this enzyme has been renamed as elastase -1. 7. Pancreatic elastase is formed by activation of proelastase from mammalian pancreas by trypsin. 8. Elastase 3B may also function in the intestinal transport and metabolism of cholesterol.9. Elastase 3A may also function in the intestinal transport and metabolism of cholesterol.10. To date, elastase 1 expression has only been detected in skin keratinocytes.
