  • PubMed Abstract: 

    The crystal structure of human rac1, a member of the rho family of small G-proteins, complexed with the non-hydrolysable GTP analogue, guanosine-5'-(beta gamma-imino)triphosphate (GMPPNP), has been determined by X-ray analysis at a resolution of 1.38 A. Comparison with the structure of H-ras indicates that rac1 has an extra alpha-helical domain that is characteristic of the rho G proteins, and may be involved in the signalling pathway of this family.
