The helicase pursuits of the eIF4AIIG/T and eIF4AIIIP/T mutants are resistant to hippuristanol. Helicase assays were done with recombinant protein (.4 mM) and duplexed RNA as explained in the Materials and Strategies
RNA in the existence of hippuristanol. 32P-labelled CAT RNA was cross-linked to .5 mg of the indicated recombinant protein in the presence or absence of hippuristanol, divided by SDSPAGE, and…
