==Crystal Structure of PilF : Functional implication in the type 4 pilus biogenesis in Pseudomonas aeruginosa==
-
PilF is a requisite protein involved in the type 4 pilus biogenesis system from the Gram-negative human pathogenic bacteria, Pseudomonas aeruginosa. We determined the PilF structure at a 2.2A resolution; this includes six tandem tetratrico peptide repeat (TPR) units forming right-handed superhelix. PilF structure was similar to the heat shock protein organizing protein, which interacts with the C-terminal peptide of Hsp90 and Hsp70 via a concave Asn ladder in the inner groove of TPR superhelix. After simulated screening, the C-terminal pentapeptides of PilG, PilU, PilY, and PilZ proved to be a likely candidate binding to PilF, which are ones of 25 necessary components involved in the type 4 pilus biogenesis system. We proposed that PilF would be critical as a bridgehead in protein-protein interaction and thereby, PilF may bind a necessary molecule in type 4 pilus biogenesis system such as PilG, PilU, PilY, and PilZ.

[https://www.uniprot.org/uniprot/PILF_PSEAE PILF_PSEAE] Essential component of the type IV pilus (T4P) that plays a role in surface and host cell adhesion, colonization, biofilm maturation, virulence, and twitching, a form of surface-associated motility facilitated by cycles of extension, adhesion, and retraction of T4P fibers (PubMed:8973346). Plays an essential role in the outer membrane localization and assembly of PilQ into secretins which are dodecamers of PilQ (PubMed:23547883, PubMed:18776008).<ref>PMID:18776008</ref> <ref>PMID:23547883</ref> <ref>PMID:8973346</ref>
