| + | [https://www.uniprot.org/uniprot/CTEC_CHRVO CTEC_CHRVO] ADP-ribosyltransferase that specifically modifies host ubiquitin on 'Thr-66' residue, which causes the shutdown of polyubiquitin synthesis and disrupts the recognition and reversal of polyubiquitin in host cells during infection (PubMed:32330457). Threonine ADP-ribosylation of ubiquitin prevents the transfer of ubiquitin from ubiquitin-activating enzyme E1 to ubiquitin-conjugating enzyme E2, which inhibits subsequent ubiquitin activation and leads to the shutdown of polyubiquitin synthesis in host cells (PubMed:32330457). The modification also causes dysfunction of polyubiquitin chains in cells, thereby blocking host ubiquitin signaling (PubMed:32330457). ADP-ribosylation by CteC is likely irreversible (PubMed:32330457). Plays a crucial role in bacterial colonization in mice during infection (PubMed:32330457).<ref>PMID:32330457</ref> | ||
