Backbone dynamics of the major tacrolimus (FK506) binding protein (FKBP-12, 107 amino acids) have been studied using 15N relaxation data derived from proton-detected two-dimensional 1H-15N NMR spectroscopy. 15N spin-lattice relaxation rate constants (R1), spin-spin relaxation rate constants (R2), and heteronuclear NOEs were determined for over 85% of the backbone amide 15N nuclei. A model free formalism [Lipari, G., & Szabo, A. (1982) J. Am. Chem. Soc. 104, 4546-4559; Lipari, G., & Szabo, A. (1982) J. Am. Chem. Soc. 104, 4559-4570] was used to derive values for the generalized order parameter (S2), the effective correlation time for internal motions (tau e), and the chemical exchange line width (Rex) for each N-H bond vector. The final optimized overall correlation time (tau m) was 9.2 ns. The average order parameter (S2) describing the amplitude of motions on the picosecond time scale was found to be 0.88 +/- 0.06. Motions on the picosecond time scale are restricted at the N and C termini, consistent with previous NMR structural studies indicating well-defined beta-strands in these regions. With the exception of the flap region from resides 82 to 87, no regions appear to be significantly disordered on the picosecond time scale. Residues in several regions of the protein exhibit high Rex terms, indicating possible motions on the millisecond to microsecond time scale due to chemical exchange and/or conformational averaging effects. Possible effects of tacrolimus (FK506) binding on FKBP-12 dynamics are discussed in the context of previously determined solution structures for FKBP-12 in the uncomplexed [Michnick et al. (1991) Science 252, 836-839; Moore et al. (1991) Nature 351, 248-250] and complexed [Meadows et al. (1993) Biochemistry 32, 754-765] states.

Abstract
Nuclear Magnetic Resonance (NMR) relaxation is a powerful technique that provides information about internal dynamics associated with configurational energetics in proteins, as well as site-specific information involved in conformational equilibria. In particular, (15)N relaxation is a useful probe to...
