Structure of Type VI immunity protein Tdi1 (Atu4351) from ''Agrobacterium tumefaciens'' is composed a GAD-like domain inserted by a DUF1851 domain, and such domain organization is rare in known structures. There is a positive groove that is mainly located in the GAD-like domain that may be associated with nucleotide-binding. | Structure of Type VI immunity protein Tdi1 (Atu4351) from ''Agrobacterium tumefaciens'' is composed a GAD-like domain inserted by a DUF1851 domain, and such domain organization is rare in known structures.

The GAD-like domain and the DUF1851 domain are shown in orange and cyan, respectively. The GAD-like domain structure is composed a seven-stranded twisted antiparallel β-sheet (β1↑-β2↓-β3↑-β4↓-β5↑-β6↓-β7↑) in the N-terminus and a two-stranded antiparallel β-sheet (β10↓-β11↑) in the C-terminus, surrounded by six helices (α1-α5 and η1) (Fig. 1a). The DUF1851 domain is composed of a two-stranded antiparallel β-sheet (β8↓-β9↑) and four helices (η2-η3 and α6-α7). Therefore, the DUF1851 domain probably exists as an insertion of the GAD-like domain rather than an independent domain. |
