2fi7 is a 2 chain structure with sequence from Pseudomonas aeruginosa PAO1. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
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).[1][2][3]
