GO
GO:0015473 A porin that acts in the assembly of fimbria together with fimbrial chaperone. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0005515 Binding to a protein. GO:0009297 The assembly from its constituent parts of a pilus, a short filamentous structure of 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:0009279 A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
