Organism
Pseudomonas savastanoi pv. phaseolicola
Function
Harpins are proteins able to elicit hypersensitive response (HR) in non-host plants and are required for pathogenicity in host plants. HrpZ forms ion-conducting pores permeable for cations. Such pore-forming activity may allow nutrient release and/or delivery of virulence factors during bacterial colonization of host plants. Also binds peptides, which contain tryptophan and leucine, suggesting a protein-protein interaction between the harpin and a host plant protein, possibly involved in the bacterial pathogenesis.
Similarity
Belongs to the harpin HrpZ family.
