| + | [https://www.uniprot.org/uniprot/CCDA_ECOLI CCDA_ECOLI] Antitoxin component of a toxin-antitoxin (TA) module which inhibits the post-segregational killing (PSK) of plasmid-free cells, also referred to as a plasmid addiction system. Labile antitoxin with a half-life of about 1 hour in the presence of CcdB. Binds to and blocks the activity of CcdB; will also remove bound CcdB protein from the CcdB-GyrA complex by forming a CcdA-CcdB complex, a process termed rejuvenation. The N-terminal 36 residues are not required for rejuventation. Functions as a transcriptional corepressor for the ccdAB operon, repression also requires CcdB.<ref>PMID:6327993</ref> <ref>PMID:2651399</ref> <ref>PMID:6308648</ref> <ref>PMID:2615761</ref> <ref>PMID:1324324</ref> <ref>PMID:8604132</ref> <ref>PMID:19647513</ref> | ||
