CC   -!- FUNCTION: Toxic component of a type II toxin-antitoxin (TA) system. Its
CC       toxic effect is neutralized by coexpression with cognate antitoxin
CC       ParD3 but no other ParD or RelB antitoxin.
CC       {ECO:0000269|PubMed:20487277}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype when deleted singly or as
CC       the parDE3 operon. {ECO:0000269|PubMed:20487277}.
CC   -!- SIMILARITY: Belongs to the RelE toxin family. {ECO:0000305}.
