The secondary structure of the 5′ UTR of sam1 RNA. (A) DMS probing analysis of the sam1 UTR RNA in the absence of SAM. (B) DMS probing analysis of the sam1 UTR RNA in the presence of SAM. (C) Predicted secondary structure of the sam1 UTR RNA by computational folding and structure probing analysis; DMS reactive nucleotides are labeled in green.
