Three-dimensional structure of p21H-ras and its implications.

Seminars in cancer biology - 1 Aug 1992

Wittinghofer F

Abstract excerpt

The three-dimensional structure of the H-ras oncogene product p21 has been determined in both its active, GTP-bound and its inactive, GDP-bound forms. This has supplied a wealth of information on the mode of binding of guanine nucleotides, on the mechanism of the GTPase reaction and on the conformational change of the protein which accompanies GTP hydrolysis. The structural analysis has also given clues to the...
