C, D	PF05016	ParE toxin of type II toxin-antitoxin system, parDE (ParE_toxin)	ParE toxin of type II toxin-antitoxin system, parDE	ParE is the toxin family of a type II toxin-antitoxin family. It is toxic towards DNA gyrase, but is neutralised by the antitoxin ParD. The family also encompasses RelE/ParE described in [2].	Domain
