| EC Number | 3.4.22.33 |
| CAS Registry Number | 9001-00-7 |
| Comments | From the pineapple plant,?Ananas comosus. Scarcely inhibited by chicken cystatin. Another cysteine endopeptidase, with similar action on small molecule substrates, pinguinain (formerly EC?3.4.99.18), is obtained from the related plant,?Bromelia pinguin, but pinguinain differs from fruit bromelain in being inhibited by chicken cystatin [4]. In peptidase family?C1?(papain family). Formerly EC?3.4.22.5?and included in EC?3.4.22.4. |

| History | |
| Reactions | Hydrolysis of proteins with broad specificity for peptide bonds. Bz-Phe- Val-Arg-|-NHMec is a good synthetic substrate, but there is no action on Z-Arg-Arg-|-NHMec (c.f. stem bromelain). |
