8.B.24.1.2	Colicin N immunity Protein of 131 aas and 3 or 4 TMSs	Bacteria	Proteobacteria	Imm of E. coli
8.B.24.1.3	Putative Colicin Immunity protein of 148 aas and 4 TMSs.	Bacteria	Proteobacteria	Imm of Providencia alcalifaciens
8.B.24.1.4	Immunity protein, ImnH, of 184 aas and 4 TMSs; provides immunity to the colicin-like pore-forming domain protein, PmnH (TC#1.C.1.3.6) (Ghequire et al. 2017).	Bacteria	Proteobacteria	ImnH of Pseudomonas synxantha
8.B.24.1.5	Colicin U immunity protein, Cui, of 174 aas and 4 TMSs (Smajs et al. 2006).	Bacteria	Proteobacteria	Cui of Shigella boydii
8.B.24.2.1	Colicin Ib immunity protein of 127 aas and 3 TMSs, Imm.	Bacteria	Proteobacteria	Imm of E. coli

8.B.24.2.3	Uncharacted protein of 103 aas and 3 TMSs	Bacteria	Proteobacteria	UP of Aeromonas hydrophila
8.B.24.2.4	Uncharacterized protein of 131 aas and 3 TMSs	Bacteria	Proteobacteria	UP of Aggregatibacter actinomycetemcomitans
8.B.24.2.5	Uncharacterized protein of 117 aas and 4 TMSs	Bacteria	Proteobacteria	UP of Salmonella enterica subsp. enterica serovar Tallahassee
8.B.24.2.6	Colicin immunity protein of 119 aas and 3 TMSs, Imm.	Bacteria	Proteobacteria	Imm of E. coli
8.B.24.3.1	Colicin M Immunity Protein of 141 aas and 1 TMSs. Cmi. This protein is able to protect a cell that harbors the plasmid ColBM-Cl139 encoding colicin M, against colicin M. Colicin M (Cma) is inactivated by interaction with Cmi. The structure of Cmi has been solved at a resolution of 1.95Å. The monomeric structure consists of a long N-terminal α-TMS and a four-stranded C-terminal β-sheet. Dimerization is mediated by an extended interface of hydrogen bond interactions between the α-helix and the four-stranded β-sheet of the symmetry related molecule. Two intermolecular disulfide bridges covalently connect this dimer to lock this complex (Usón et al. 2012).	Bacteria	Proteobacteria	Cmi of E. coli
8.B.24.3.2	YebF homologue of 119 aas and 1 TMS.	Bacteria	Proteobacteria	YebF homologue of Hafnia alvei
8.B.24.3.3	Uncharacterized protein of 113 aas and 1 TMS.	Bacteria	Proteobacteria	UP of Salmonella enterica
8.B.24.4.1	Colicin E3 immunity protein of 85 aas and 0 TMSs, Imm3, Imm, ImmB, CeiC.	Bacteria	Proteobacteria	ImmB (CeiC) of E. coli
8.B.24.4.2	Cloacin of 92 aas and 0 TMSs.	Bacteria	Proteobacteria	Cloacin of Pseudomonas fluorescens
8.B.24.4.3	Uncharacterized protein of 79 aas and 0 TMSs	Bacteria	Cyanobacteria	UP of Synechococcus sp.
