Solution NMR-derived global fold of a monomeric 82-kDa enzyme.
V.Tugarinov, W.Y.Choy, V.Y.Orekhov, L.E.Kay.
The size of proteins that can be studied by solution NMR spectroscopy has increased significantly because of recent developments in methodology. Important experiments include those that make use of approaches that increase the lifetimes of NMR signals or that define the orientation of internuclear bond vectors with respect to a common molecular frame. The advances in NMR techniques are strongly coupled to isotope labeling methods that increase sensitivity and reduce the complexity of NMR spectra. We show that these developments can be exploited in structural studies of high-molecular-weight, single-polypeptide proteins, and we present the solution global fold of the monomeric 723-residue (82-kDa) enzyme malate synthase G from Escherichia coli, which has been extensively characterized by NMR in the past several years.

Figure 1.
Fig. 1. Representative planes from 4D NOE data sets. (a)F[1](1H)--F[2](13C) plane from the 4D CH[3]--CH[3] NOESY spectrum showing correlations to L433 1. (b) The correlation involving L577 1 can be assigned despite the fact that this residue is in a very crowded region of the 2D 1H--13C correlation map. (c)F[3](15N)--F[4](1HN) plane from the HN--HN 4D data set showing correlations to Lys 206 HN. (d)F[3](15N)--F[4](1HN) plane from the methyl--HN 4D matrix, showing NOEs between I200 1 and proximal amide protons.

Fig. 2. Comparison of x-ray and NMR-derived structures of MSG. (a) Ribbon diagrams of the x-ray structure of MSG (Left, PDB ID code 1D8C [PDB] ; ref. 17) and the lowest energy NMR structure (Right) calculated on the basis of 1,531 NOE, 1,101 dihedral angle, 415 residual dipolar couplings, and 300 carbonyl-shift restraints. (b) Ribbon representations of MSG (Left shows x-ray structure, and Right shows the lowest-energy NMR structure) are shown with the C carbons of residues that either contact or are proximal to glyoxylate (D270, E272, R338, E427, F453, L454, D455, and D631) in the active site of the protein, indicated with red spheres. The image was prepared by using MOLMOL (39).

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.
