Svx Peptidases of Phytopathogenic Pectolytic Bacteria: Structural, Catalytic and Phytoimmune Properties.

Svx proteins are virulence factors secreted by phytopathogenic bacteria of the genus into the host plant cell wall. Svx-encoding genes are present in almost all species of the soft rot Pectobacteriaceae ( and genera). The Svx of () has been shown to be a gluzincin metallopeptidase that presumably targets plant extensins, proteins that contribute to plant cell wall rigidity and participate in cell signaling.

Structure-Functional Characteristics of the Svx Protein-The Virulence Factor of the Phytopathogenic Bacterium .

The Svx proteins are virulence factors of phytopathogenic bacteria of the genus. The specific functions of these proteins are unknown. Here we show that most of the phytopathogenic species of , , and genera have genes encoding Svx proteins, as well as some plant-non-associated species of different bacterial genera.
