ThsA has robust NAD+ cleavage activity and and a two-domain architecture containing a N-terminal NAD-binding domain (denoted as sirtuin-like or Macro) and C-terminal SLOG-like domain. In some instances, such as in B. amyloliquefaciens ThsA has an N-terminal transmembrane domain [1]. ThsB (also referred to as TIR1 and TIR2) is structurally similar to TIR domain proteins but without enzymatic activity. This is the TIR-like domain of ThsB proteins, which adopts a Rossmann-like fold. ThsB is responsible for recognizing phage infection [2].
