== Function ==
[https://www.uniprot.org/uniprot/DDDA_BURC1 DDDA_BURC1] Toxic component of a toxin-immunity protein module, which functions as a cellular contact-dependent growth inhibition (CDI) system. CDI modules allow bacteria to communicate with and inhibit the growth of closely related neighboring bacteria in a contact-dependent fashion. Bacteria that have this module inhibit or kill bacteria without it, giving them a growth advantage. Probably specifically inhibited by cognate immunity protein DddI (Probable). The C-terminal 163 residue fragment has double-stranded DNA cytidine deaminase activity; it does not deaminate ssDNA, ssRNA or dsRNA. Leads to C:G to T:A conversions in deaminated DNA. Preferentially deaminates 5'-TC-3' substrates (PubMed:32641830).<ref>PMID:32641830</ref>
