Crystal Structure of PilF : Functional implication in the type 4 pilus biogenesis in Pseudomonas aeruginosa
Overview
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.
