Probable outer membrane usher protein ElfC

Gene

elfC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Part of the elfADCG-ycbUVF fimbrial operon, which promotes adhesion of bacteria to different abiotic surfaces. Could be involved in the export and assembly of the ElfA fimbrial subunits across the outer membrane.1 Publication

Miscellaneous

The operon is cryptic under classical laboratory conditions, but is functional when constitutively expressed.1 Publication
