Protein Family Models

The epsilon antitoxin, produced by various prokaryotes, forms part of a postsegregational 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 that directly interacts with the zeta toxin, inactivating it [1]. [1]. 12571357.
