Protein Domain : Saf-pilin pilus formation protein IPR018569

Type	Domain
Description	This domain consists of the adjacent Saf-Nte and Saf-pilin chains of the pilus-forming complex. Pilus assembly in Gram-negative bacteria involves a Donor-strand exchange mechanism between the C- and the N-termini of this domain. The C-terminal subunit forms an incomplete Ig-fold which is then complemented by the 10-18 residue N terminus of another, incoming, pilus subunit which is not involved in the Ig-fold. The N terminus sequences contain a motif of alternating hydrophobic residues that occupy the P2 to P5 binding pockets in the groove of the first pilus subunit [ ].
Short Name	Saf-pilin_pilus_formation
