Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 1.66Å Ligands: AR6, NCA, SCN Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function DART_THES0 Toxic component of a hybrid type II/IV toxin-antitoxin (TA) system. ADP-ribosylates ssDNA on the second thymidine of the consensus sequence 5'-TNTC-3'; the protein does not auto-modify. Arg-51 is highly flexible, allowing it to assume multiple positions in the crystal structures (PubMed:34408320). Its toxic effect is neutralized by cognate antitoxin DarG (By similarity).[UniProtKB:O53604]
