Protein Family Models

This family of domains contain only a P-loop motif, that is characteristic of the AAA superfamily. Many of the proteins in this family are just short fragments so there is no Walker B motif. (from Pfam)

This family consists of several bacterial zeta toxin proteins. Zeta toxin is thought to be part of a postregulational killing system in bacteria. It relies on antitoxin/toxin systems that secure stable inheritance of low and medium copy number plasmids during cell division and kill cells that have lost the plasmid [1]. [1]. 12571357.
