Effects of polyvalent cations on the folding of an rRNA three-way junction and binding of ribosomal protein S15.

RNA (New York, N.Y.) - 1 Aug 1998

Batey R T, Williamson J R

Abstract excerpt

The Bacillus stearothermophilus ribosomal protein S15 binds to a phylogenetically conserved three-way junction formed by the intersection of helices 20, 21, and 22 of eubacterial 16S ribosomal RNA, inducing a large conformational change in the RNA. Like many RNA structures, this three-way junction can also be folded by the addition of polyvalent cations such as magnesium, as demonstrated by comparing the...
