YagB' is related to the prophage-encoded antitoxin genes yfjZ (CP4-57), yafW (CP4-6), and cbeA(yeeU) (CP4-44). The ISX' element has apparently deleted the end of yagB, fusing it to 13 insX' codons to make a 116 fusion pseudogene that may be expressed. The cognate toxin appears to have been deleted.
