Solution structure of the Methanococcus thermolithotrophicus FKBP
Overview
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.
