UniProtKB description:  Antitoxin component of a type II toxin-antitoxin (TA) system (PubMed:18398006, PubMed:24141193, PubMed:18757857). A labile antitoxin that binds to cognate doc toxin and neutralizes its ability to phosphorylate host EF-Tu. Does not reverse phosphorylation. Bacteriophage P1 lysogenizes bacteria as a low-copy number plasmid; phd and doc proteins function in unison to stabilize plasmid number by inducing a lethal response to P1 plasmid prophage loss (PubMed:8411153).
