Before revision:  By adapting direct coupling analysis (DCA) to\betaDCA  treat in tandem sequences written in two alphabets, nucleotides and amino acids \betaDCA , we could analyze StpA-RNA interactions and show consistency with a previously proposed two-pronged mechanism: StpA disrupts specific positions in the group I intron while globally and loosely binding to the entire structure.

With \alpha\betaDCA , we could analyze StpA-RNA interactions and show consistency with a previously proposed two-pronged mechanism: StpA disrupts specific positions in the group I intron while globally and loosely binding to the entire structure.
