Magnesium-dependent alternative foldings of active and inactive Escherichia coli tRNA(Glu) revealed by chemical probing.
A stable conformer of Escherichia coli tRNA(Glu), obtained in the absence of Mg(2+), is inactive in the aminoacylation reaction. Probing it with diethylpyrocarbonate, dimethyl sulfate and ribonuclease V1 revealed that it has a hairpin structure with two internal loops; the helical segments at both e...
