in this investigation , recombinant ras genes have been constructed between the 5 ' p21 coding region of normal ( ec ) or oncogenically activated ( ej ) human c-ha-ras-1 and the 3 ' p21 coding region of v-ha-ras to generate p21 molecules containing a threonine phosphoacceptor site at position 59 and a glycine ( ec/v-ha ) or valine ( ej/v-ha ) at residue 12 .
