free- and ef-2-bound 80 s ribosomes , within the high-affinity complex with the non-hydrolysable gtp analog : guanylylmethylenediphosphonate ( guopp ( ch2 ) p ) , and the low-affinity complex with gdp , were treated with trypsin under conditions that modified neither their protein synthesis ability nor their sedimentation constant nor the bound ef-2 itself .
