Chains	Accession	Name	Description	Comments	Source
A [auth D], B [auth E]	PF13304	AAA domain, putative AbiEii toxin, Type IV TA system (AAA_21)	AAA domain, putative AbiEii toxin, Type IV TA system	Several members are annotated as being of the abortive phage resistance system, in which case the family would be acting as the toxin for a type IV toxin-antitoxin resistance system.
