Protein
D-methionine transport system permease protein MetI
Organism
Escherichia coli (strain K12)
Function
(Microbial infection) Probably transports the toxic C-terminal region of CdiA from E.coli strain MHI813 across the inner membrane to the cytoplasm, where CdiA has a toxic effect. Toxin transport is strain-specific, mutations in this gene do not confer resistance to several other tested CdiA toxins.
Similarity
Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
