| APIS012 | tifA | toxin-antitoxin (TA) | CLAN022 | T4 of E. coli | PMID:35924892 | Original gene 61.4, experimentally evolved T4 phage to overcome a phage-defensive toxin-antitoxin system (toxIN) in E. coli. Through recombination, T4 rapidly acquires segmental amplifications of a previously uncharacterized gene, now named tifA, encoding an inhibitor of the toxin, ToxN. |
