Description | This superfamily includes the colicin M immunity protein Cmi, and the protein of unknown function YebF. Cmi protects cells from the colicin M toxin, though the mechanism by which it achieves this is not known [ ]. The protein forms an α-β fold and contains a disulphide bond that is essential for function []. Although the function of YbeF is not known, it is secreted by E. coli, and contains the two conserved cysteine residues responsible for the disulphide bond in Cmi []. | Name | YebF/Cmi superfamily |
Short Name | YebF/Cmi_sf | Type | Homologous_superfamily |
