| leupeptin | A peptide (N-acetylleucylleucylarginyl) from Streptomyces species that inhibits cathepsin B, papain, trypsin, plasmin, and cathepsin D. (05 Mar 2000) |
|---|---|
| leupeptin acid reductase | <enzyme> Converts leupeptin acid (acetyl-l-leu-l-leu-l-arg) into leupeptin (acetyl-l-leu-l-leu-l-arginal); requires ATP and NADPH Registry number: EC 1.2.1.- (26 Jun 1999) |
| leupeptin acid synthetase | <enzyme> ATP essential for reaction Registry number: EC 6.3.2.- (26 Jun 1999) |
| leupeptinase | <enzyme> Serine protease active at neutral pH; inhibited by isoflurophate and phenylmethylsulfonyl fluoride Registry number: EC 3.4.21.- (26 Jun 1999) |
| leupeptins | <chemical> A group of acylated oligopeptides produced by actinomycetes that function as protease inhibitors. They have been known to inhibit to varying degrees trypsin, plasmin, kallikrein, papain and the cathepsins. Pharmacological action: protease inhibitors. (12 Dec 1998) |
