NMR solution structure and dynamics of the peptidyl-prolyl cis-trans isomerase domain of the trigger factor from Mycoplasma genitalium compared to FK506-binding protein.

We have solved the solution structure of the peptidyl-prolyl cis-trans isomerase (PPIase) domain of the trigger factor from Mycoplasma genitalium by homo- and heteronuclear NMR spectroscopy. Our results lead to a well-defined structure with a backbone rmsd of 0.23 A. As predicted, the PPIase domain of the trigger factor adopts the FK506 binding protein (FKBP) fold. Furthermore, our NMR relaxation data indicate that the dynamic behavior of the trigger factor PPIase domain and of FKBP are similar. Structural variations when compared to FKBP exist in the flap region and within the bulges of strand 5 of the beta sheet. Although the active-site crevice is similar to that of FKBP, subtle steric variations in this region can explain why FK506 does not bind to the trigger factor. Sequence variability (27% identity) between trigger factor and FKBP results in significant differences in surface charge distribution and the absence of the first strand of the central beta sheet. Our data indicate, however, that this strand may be partially structured as "nascent" beta strand. This makes the trigger factor PPIase domain the most minimal representative of the FKBP like protein family of PPIases.

Figure 8. Superposition of the lowest-energy solution structure of TF[PPIase] (blue) and the X-ray structure of FKBP (red). For FKBP the N terminus (residues 1-15) is omitted for clarity. Coordinates for FKBP were taken from the FKBP-FK506 complex, PDB entry 1FKF. The structures were superimposed using residues marked by asterisks in Figure 6, resulting in an rmsd value of 1.3 Å.
Figure 10.
Figure 10. Model of the hypothetical TF[PPIase]-FK506 complex (left) and comparison with the actual FKBP-FK506 complex (right). The hypothetical TF[PPIase]-FK506 complex is based upon the same superposition of TF[PPIase] and FKBP as in Figure 8. Regions of FK506 and of TF[PPIase] experiencing steric clashes are indicated by their dotted van der Waals surfaces. Blue, residues Phe66 and Tyr93 (TF[PPIase]) that interfere with the binding in TF[PPIase] and the corresponding Val55 and Tyr82 of FKBP. Regions of FK506 in conflict with the binding to TF[PPIase] are displayed in red and green, respectively, and are colored according to Scheme 1.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
