Minimum energy path for a U6 RNA conformational change involving protonation, base pair rearrangement and base flipping

The U6 RNA internal stem-loop (U6 ISL) is a highly conserved domain of the spliceosome that is important for pre-mRNA splicing. The U6 ISL contains an internal loop that is in equilibrium between two conformations controlled by the protonation state of an adenine (pKa = 6.5). Lower pH favors formati...
