Xylella fastidiosa plasmid-encoded PemK toxin is an endoribonuclease.

Phytopathology - 1 Jan 2012

Lee Min Woo, Rogers Elizabeth E, Stenger Drake C

Abstract excerpt

Stable inheritance of pXF-RIV11 in Xylella fastidiosa is conferred by the pemI/pemK toxin-antitoxin (TA) system. PemK toxin inhibits bacterial growth; PemI is the corresponding antitoxin that blocks activity of PemK by direct binding. PemK and PemI were overexpressed in Escherichia coli and activities of each were assessed. Purified PemK toxin specifically degraded single-stranded RNA but not double-stranded RNA,...
