| + | [https://www.uniprot.org/uniprot/DOC_BPP1 DOC_BPP1] Toxic component of a toxin-antitoxin (TA) module. Overexpression results in inhibition of growth in liquid cultures and a decrease in colony formation by inhibiting translation, stabilizing mRNA and polysomes; these effects are overcome by concomitant expression of antitoxin phd. Binds 70S ribosomes and the 30S ribosomal subunits, the binding site is the same as for the antibiotic hygromycin B. Bacteriophage P1 lysogenizes bacteria as a low-copy number plasmid. Doc and phd proteins function in unison to stabilize plasmid number by inducing a lethal response to P1 plasmid prophage loss. Overexpression of doc can induce the mRNA interferase activity of RelE in vivo.<ref>PMID:9829946</ref> <ref>PMID:18398006</ref> Antitoxin phd binds to its own promoter repressing its expression; toxin doc acts as a corepressor or derepressor depending on the ratio, repressing or inducing expression.<ref>PMID:9829946</ref> <ref>PMID:18398006</ref> | ||
