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).
