Bacterial epsilon antitoxin (IPR015090)

Short name: Epsilon_antitox

Family relationships

None.

Description

The epsilon antitoxin, produced by various prokaryotes, forms part of a post-segregational killing system, which is involved in the initiation of programmed cell death of plasmid-free cells. The protein is folded into a three-helix bundle directly interacting with the zeta toxin, inactivating it [PMID: 12571357].
