(2R,3S)-β-Hydroxyleucine is a nonprotein amino acid. (2R,3S)-β-Hydroxyleucineis an inhibitor of serine protease. In particular, (2R,3S)-β-Hydroxyleucine was effective in inhibiting trypsin and proteinase K of the serine proteases group. (2R,3S)-β-Hydroxyleucine was not able to inhibit the growth of gram-positive and gram-negative bacteria and yeasts unlike its (2S,3R)-isomer.
