Solution-state NMR investigations of triosephosphate isomerase active site loop motion: ligand release in relation to active site loop dynamics.
S.Rozovsky, G.Jogl, L.Tong, A.E.McDermott.
Product release is partially rate determining in the isomerization reaction catalyzed by Triosephosphate Isomerase, the conversion of dihydroxyacetone phosphate to D-glyceraldehyde 3-phosphate, probably because an active-site loop movement is necessary to free the product from confinement in the active-site. The timescale of the catalytic loop motion and of ligand release were studied using 19F and 31P solution-state NMR. A 5'-fluorotryptophan was incorporated in the loop N-terminal hinge as a reporter of loop motion timescale. Crystallographic studies confirmed that the structure of the fluorinated enzyme is indistinguishable from the wild-type; the fluorine accepts a hydrogen bond from water and not from a protein residue, with minimal perturbation to the flexible loop stability. Two distinct loop conformations were observed by 19F NMR. Both for unligated (empty) and ligated enzyme samples a single species was detected, but the chemical shifts of these two distinct species differed by 1.2 ppm. For samples in the presence of subsaturating amounts of a substrate analogue, glycerol 3-phosphate, both NMR peaks were present, with broadened lineshapes at 0 degrees C. In contrast, a single NMR peak representing a rapid average of the two species was observed at 30 degrees C. We conclude that the rate of loop motion is less than 1400 s(-1) at 0 degrees C and more than 1400 s(-1) at 30 degrees C. Ligand release was studied under similar sample conditions, using 31P NMR of the phosphate group of the substrate analogue. The rate of ligand release is less than 1000 s(-1) at 0 degrees C and more than 1000 s(-1) at 30 degrees C. Therefore, loop motion and product release are probably concerted and likely to represent a rate limiting step for chemistry.

Figure 1.
Figure 1. (a) The superposition of loop 6 from both the wild-type yeast TIM structure (PDB entry 1YPI [Lolis et al 1990]) and the Trp90Tyr Trp157Phe with 5'-fluorotryptophan incorporated at position 168 are shown. Loop 6 backbone is identical in both structures. A slight variation is found in Ile170 side-chain, which is not unusual for a solvent exposed side-chain. (b) The electron density of the 5'-fluorotryptophan incorporated into a single location on TIM's flexible loop is shown. The presence of the fluorine atom does not modify the hydrophobic packing and hydrogen bonding interactions observed for the unmodified tryptophan in the wild-type yeast TIM [Lolis et al 1990]. A water molecule is within hydrogen bond distance from the fluorine atom in both subunits. Graphical representations were prepared with the program MOLSCRIPT [Kraulis 1991] and RASTER3D [Merritt and Bacon 1997].
Figure 4.
Figure 4. Lineshape simulations for the flexible loop 5'-fluorotryptophan 19F resonance (at 9.4 T, Figure 2 right panel, reproduced for convenience on the left). The unligated state can be simulated with two sites corresponding to the open and closed loop's conformation, at any arbitrary skewed populations, assuming that the unligated enzyme is not likely to close on an unligated active-site. Loop motion in the present of G3P was simulated using a three site model and constraint from kinetic data. Loop opening rate is 1000 s -1 at 0°C and 5000 s -1 at 30°C. Line broadening used in the simulation is 10 Hz. The T[2]-induced linewidth is certainly borader, but has not been considered here. Populations of the loop conformations were selected based on sample conditions; the encounter complex occupancy is assumed to be 1 % of the closed loop enzyme occupancy. Simulations are scaled in a manner analogous to the experimental data.

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 codes are shown on the right.
