CC -!- FUNCTION: Major component of the type IV fimbriae that plays an
CC essential role in twitching motility, natural transformation, and
CC protease secretion. {ECO:0000250|UniProtKB:A5EWR9}.
CC -!- SUBUNIT: The pili are polar flexible filaments of about 5.4 nanometers
CC diameter and 2.5 micrometers average length; they consist of only a
CC single polypeptide chain arranged in a helical configuration of five
CC subunits per turn in the assembled pilus.
CC -!- SUBCELLULAR LOCATION: Fimbrium {ECO:0000250|UniProtKB:A5EWR9}. Membrane
CC {ECO:0000255}; Single-pass membrane protein {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the N-Me-Phe pilin family. {ECO:0000305}.
