Three-dimensional Solution Structure of an Archaeal FKBP with a Dual Function of Peptidyl Prolyl cis-trans Isomerase and Chaperone-like Activities
J.MOL.BIOL., 328:1149-1160, 2003

PubMed Abstract: Here we report the solution structure of an archaeal FK506-binding protein (FKBP) from a thermophilic archaeum, Methanococcus thermolithotrophicus (MtFKBP17), which has peptidyl prolyl cis-trans isomerase (PPIase) and chaperone-like activities, to reveal the structural basis for the dual function. In addition to a typical PPIase domain, a newly identified domain is formed in the flap loop by a 48-residue insert that is required for the chaperone-like activity. The new domain, called IF domain (the Insert in the Flap), is a novel-folding motif and exposes a hydrophobic surface, which we consider to play an important role in the chaperone-like activity.
