| Enzyme Function | FUNCTION: Involved in plant defense against Phytophtora parasitica (PubMed:28082413). Contributes positively to Nicotiana resistance against P.parasitica (PubMed:28082413). Binds the P.parasitica xyloglucanase XEG1 and inhibits its cell wall degrading enzyme activity and its contribution as P.parasitica virulence factor (PubMed:28082413). XEG1 acts as an important virulence factor during P.parasitica infection but also acts as a pathogen-associated molecular pattern (PAMP) in Nictotiana species, where it can trigger defense responses including cell death (PubMed:28082413). {ECO:0000269|PubMed:28082413}.; FUNCTION: (Microbial infection) Possesses stronger binding affinity with XLP1, a truncated paralog of P.parasitica XEG1 which has no enzyme activity. Is impaired in its inhibitor activity towards the P.parasitica xyloglucanase XEG1 when hijacked by XLP1 binding. {ECO:0000269|PubMed:28082413}. |
