The Ras-RasGAP complex: structural basis for GTPase activation and its loss in oncogenic Ras mutants.
K.Scheffzek, M.R.Ahmadian, W.Kabsch, L.Wiesmüller, A.Lautwein, F.Schmitz, A.Wittinghofer.
The three-dimensional structure of the complex between human H-Ras bound to guanosine diphosphate and the guanosine triphosphatase (GTPase)-activating domain of the human GTPase-activating protein p120GAP (GAP-334) in the presence of aluminum fluoride was solved at a resolution of 2.5 angstroms. The structure shows the partly hydrophilic and partly hydrophobic nature of the communication between the two molecules, which explains the sensitivity of the interaction toward both salts and lipids. An arginine side chain (arginine-789) of GAP-334 is supplied into the active site of Ras to neutralize developing charges in the transition state. The switch II region of Ras is stabilized by GAP-334, thus allowing glutamine-61 of Ras, mutation of which activates the oncogenic potential, to participate in catalysis. The structural arrangement in the active site is consistent with a mostly associative mechanism of phosphoryl transfer and provides an explanation for the activation of Ras by glycine-12 and glutamine-61 mutations. Glycine-12 in the transition state mimic is within van der Waals distance of both arginine-789 of GAP-334 and glutamine-61 of Ras, and even its mutation to alanine would disturb the arrangements of residues in the transition state.

Fig. 2. The complex between GAP-334 and Ras. (A) Ribbon representation of the complex model drawn with Molscript (52) and^ Raster3D (53) according to the assignment of secondary structure^ elements obtained with the program DSSP (54). The extra and^ catalytic domains of GAP-334 are shown in green and red (respectively), regions of GAP contacting Ras in light brown, Ras in yellow, and^ GDP and AlF[3] as ball-and-stick models. Regions involved in the^ interface are labeled, Sw I and Sw II indicating the switch regions, C the COOH-terminal, and N the NH[2]-terminal. (B) Schematic^ drawing with selected interactions. Polar interactions between individual residues of GAP-334 and Ras are shown as red lines for interactions of side chains, and as red arrows for contacts from side chain to main chain atoms, where the arrowhead marks the residue contributing the main chain group. Yellow lines indicate^ van der Waals or hydrophobic interactions. Some water molecules (marked W) from the interface region are included. Residues belonging to the interacting regions of Ras indicated in (A) are denoted^ with specified boxes, as indicated. Interaction between Lys88 and Thr791 is shown by a dashed arrow, because the electron density in this region is presently not of sufficient quality to unambiguously define the contact. Amino acid abbreviations are in (55).

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.
