... However, the rotations around the phosphate (α, β, ε, ζ) of the 5′-aminoacyl phosphate nucleotide, which is used as a donor in non-enzymatic aminoacylation reactions, can be treated in the same way as those around the C–C single bond of ethane. That is, the rotations around the phosphate are not res ...
