FunFam 2: Outer membrane usher protein FimD

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 4 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.
GO Term Annotations Evidence
Heparin binding GO:0008201
Interacting selectively and non-covalently with heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells and which consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues.

GO Term Annotations Evidence
Pilus organization GO:0043711
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a pilus, a short filamentous structure on a bacterial cell, flagella-like in structure and generally present in many copies.

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.
