Coaxial Stacking

Example 1

 

 

example structure        

∆G°37 coaxial stack = ∆G°37(Watson-Crick Stack)

 

∆G°37 coaxial stack = ∆G°37(AU pair followed by CG pair)

 

∆G°37 coaxial stack= –2.24 kcal/mol

 

 

 

Note that at this interface, the terminal AU pair penalty would still apply when calculating the helix stability.
