WebApr 30, 1990 · The crystal structure of the H-ras oncogene protein p21 complexed to the slowly hydrolysing GTP analogue GppNp has been determined at 1.35 A resolution. 211 water molecules have been built into the electron density. The structure has been refined to a final R-factor of 19.8% for all data between 6 A and 1.35 A. The binding sites of the ... WebApr 2, 2024 · As previously stated, H-Ras structural studies served as the foundation of all information concerning Ras protein composition. This was due, in part, to the high degree of homology shared by Ras family members (82–90%; Fig. 1B). As such, introducing the structure of H-Ras is tantamount to introducing the structure of Ras in general. red haired heffer
