| Enzyme Function | FUNCTION: pEKW peptides may serve as metalloproteinase inhibitors during glandular storage. Their inhibition may be instantly disengaged, by dilution or physiochemical change, when venom is injected into tissue of the victim. {ECO:0000269|PubMed:18029259}.; FUNCTION: [C-type natriuretic peptide]: Exhibits hypotensive and vasodepressor activity. Acts by activating natriuretic receptors (NPR1 and/or NPR2 and/or NPR3) (By similarity). {ECO:0000250}. |
