Pilus a hair-like structure on the surface of bacteria which may be associated with bacterial CONJUGATION the sex pilus or with adhering bacteria to surfaces.

Pilus. Pili is a hairlike protein structure on the surface of a cell especially Gram-negative bacteria. Pilus pahy-l uhs noun plural pili pahy-lahy. Pili are primarily composed of oligomeric pilin proteins which arrange helically to form a cylinder.

Pilus a hair-like structure on the surface of bacteria which may be associated with bacterial CONJUGATION the sex pilus or with adhering bacteria to surfaces. Pilus assembly is coordinated and catalysed by elaborate multiprotein complexes that either span both the bacterial inner membrane and outer membrane or are localized in the outer membrane only2. New pilin protein molecules insert into the base of the pilus.

Specifically more fully sex pilus any of those present singly or in small numbers on the surface of Gram-negative bacteria which are encoded by conjugative plasmids and play a role in conjugation. A hair or a structure as on the surface of a bacterial cell resembling a hair Examples of pilus in a Sentence Recent Examples on the Web Maybe each of those growths. A pilus is typically 7 to 8 nm in diameter and several hundred pili can extend from the surface of a bacterial cell see image to right.

Fimbriae can be used interchangeably although some researchers reserve the term pilus for the appendage required for bacterial conjugation. Dozens of these structures can exist on the bacteria.

Cells produce a specific plasmid-coded pilus called the sex pilus which attaches the donor cell to the recipient cell. New pilin protein molecules insert into the base of the pilus. Many conjugative plasmids can.

Once connected the two cells are brought into direct contact and a conjugal bridge forms through which the DNA is transferred from the donor to the recipient.
