CC -!- FUNCTION: Plays an essential role in natural DNA transformation but is
CC not required for pilus biogenesis. {ECO:0000269|PubMed:12839734}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:Q72JC0}; Single-pass membrane protein
CC {ECO:0000255}. Cell outer membrane {ECO:0000250|UniProtKB:Q72JC0};
CC Single-pass membrane protein {ECO:0000255}. Periplasm
CC {ECO:0000250|UniProtKB:Q72JC0}. Note=The single N-terminal
CC transmembrane is initially involved in the correct localization to the
CC inner membrane. Once the leader sequence cleaved, this region plays a
CC role in multimerization and protein-protein interactions in the
CC periplasm and the outer membrane. {ECO:0000250|UniProtKB:Q72JC0}.
CC -!- DISRUPTION PHENOTYPE: Mutants have a wild-type piliation phenotype but
CC are deficient in transformation. {ECO:0000269|PubMed:12839734}.
