A method for site-selective deuteration of amino acids using a protein system having an aminotransferase (e.g., DsaD) and/or a small partner protein (e.g., DsaE). A non-deuterated amino acid is contacted with deuterium and an aminotransferase or a combination of an aminotransferase and a partner protein, to yield a Cα-deuterated or a Cα- and Cβ-deuterated amino acid. Cβ-deuterated amino acids can be accessed by contacting a Cα- and Cβ-deuterated amino acid with non-deuterium hydrogen and an aminotransferase to wash out the deuterium at the Ca carbon atom by the non-deuterium hydrogen.
