PF04221RelB antitoxin (RelB)RelB antitoxinRelE and RelB form a toxin-antitoxin system. RelE represses translation, probably through binding ribosomes ([1], [2]). RelB stably binds RelE, presumably deactivating it.Domain

PF15738Bacterial toxin of type II toxin-antitoxin system, YafQ (YafQ_toxin)Bacterial toxin of type II toxin-antitoxin system, YafQYafQ is a family of bacterial toxin ribonucleases of type II toxin-antitoxin systems. The E.coli gene is expressed from the dinB operon [1,2]. The cognate antitoxin for the E. coli protein is DinJ, in family RelB_antitoxin, Pfam:PF02604.Domain
