| Primary Information |
| PPepDB ID | PPepDB_3342 |
| Peptide Name | StAsp-PSI |
| PMID(s) | 20153392 |
| Plant Source (Scientific Name) | Solanum tuberosum |
| Plant Source (Common Name) | Potato |
| Plant Family | Solanaceae |
| Peptide Family | --NA-- |
| Peptide Function | Antimicrobial, Cytotoxic |
| Peptide Function Description | It is used to kill spores of two potato pathogens in a dose-dependent manner without any deleterious effect on plant cells, i.e. it has the ability to kill microbial pathogens on the direct interaction of the protein with the microbial cell wall/or membrane, leading to increased permeability and lysis. It is also cytotoxic to Gram-negative and Gram-positive bacteria and shows cytotoxic activity. |
