 ## Description
 
-The Rst_2TM_1TM_TIR system is carried by the P2-like phage AC1 and protects *Escherichia coli* C against lambda, LF82_P8 and P2 phages. This system is composed of three proteins, Rst_TIR_tm, that contains a TIR ( Toll/interleukin-1 receptor) domain, Rst_1TM_TIR, that contains a transmembrane helix (TM) and Rst_2TM_TIR, that contains two TMs :ref{doi=10.1016/j.chom.2022.02.018}. Rousset et al. suggested that the TIR containing protein could generate a nucleotide messenger that in turn could activate the associated transmembrane proteins.
