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.
CC   -!- MISCELLANEOUS: Moraxella bovis can express either a Q or a I pilin, the
CC       inversion of 2 kb of DNA determines which pilin is expressed.
CC   -!- SIMILARITY: Belongs to the N-Me-Phe pilin family. {ECO:0000305}.
CC   -!- CAUTION: In PubMed:2902184 it is said that 50% of the peptides have N-
CC       methyl-Phe and 50% begin with Thr-8. N-terminal methylation produces
CC       preview during Edman degradation, which makes this appear to happen
CC       when the peptide is completely N-terminally methylated. {ECO:0000305}.
