FunFam 1: Type IV pilus assembly protein PilO

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 1 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

Type IV pilus-dependent motility GO:0043107
Any process involved in the controlled movement of a bacterial cell which is dependent on the presence of type IV pili. Includes social gliding motility and twitching motility.

Type IV pilus biogenesis GO:0043683
A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a type IV pilus. A type IV pilus is composed of a pilus fiber and approximately ten proteins at its base; type IV pili play a role in cell motility, adherence to substrates, and aggregation.

Pilus assembly GO:0009297
The assembly of a pilus, a short filamentous structure on a bacterial cell, flagella-like in structure and generally present in many copies. Pili are variously involved in transfer of nucleic acids, adherence to surfaces, and formation of pellicles. Is required for bacterial conjugation, or can play a role in adherence to surfaces (when it is called a fimbrium), and in the formation of pellicles.

GO Term Annotations Evidence
Type IV pilus GO:0044096
A short filamentous structure on the surface of a bacterial cell distinguished from other pili by post-translational N-methylation of the pilin monomers.
