The small GTPase Ras plays a key role as a molecular switch in the intercellular signal transduction. On Mg(2+) --> Mn(2+) substituted samples, the first ligand sphere of the metal ion in the inactive, GDP-bound Ras has been studied by continuous wave EPR at 94 GHz (W-band). Via replacement of normal water with (17)O-enriched water, the (17)O--(55)Mn superhyperfine coupling was used to determine ...
