Binding of cAMP by an R subunit of PKA occurs in a cooperative fashion; i.e., binding of the first cAMP molecule to CNB-B lowers the Kd for binding of the second cAMP to CNB-A.

The charging of a tRNA with its cognate amino acid is a remarkably accurate process.
Experimental measurements indicate, for example, that at equal concentrations of isoleucine and valine, IleRS transfers ∼40,000 isoleucines to tRNAIle for every valine it so transfers.
