Figure 1From: New insight into the dynamic properties and the active site architecture of H-Ras p21 revealed by X-ray crystallography at very high resolutionSchematic representation of different nucleotides and relevant photolysis and hydrolysis reactions. For the non-hydrolyzable GTP analogs caged GTP and GppNHp, the modifications compared to GTP are marked in green. The chiral carbon atom leading to the diastereomers R- and S-caged GTP is marked in brown.Back to article page
