Esterification of all four monoribonucleotides with acetyl-D-L-valine proceeds with a preference for the D-isomer but the D/L ratio in the products declines as a function of the hydrophobicity of the nucleotide

Abstract

We recently reported that esterification of 5'-AMP with N-acetyl amino acids proceeds with a preference for D-amino acids, and the D/L ratio in products declines as the hydrophobicity of the amino acid declines. Using one amino acid, Ac-Val, we now show that esterification of all four nucleotides proceeds with a preference for the D-isomer and the preference declines as the hydrophobicity of the nucleotide declines. So, in both types of experiments, the preferences seem determined by hydrophobic interactions.
