In recent years, dihydrodipicolinate synthase (DHDPS, E.C. 4.2.1.52) has received considerable attention from a mechanistic and structural viewpoint. DHDPS catalyzes the reaction of (S)-aspartate-beta-semialdehyde with pyruvate, which is bound via a Schiff base to a conserved active-site lysine (Lys161 in

The chemical reactivity of various alpha-keto acid anions (beta-hydroxypyruvate, beta-phenylpyruvate, 2-ketobutyrate and 2-ketoglutarate) with hydrogen peroxide (H2O2) was investigated at physiological pH (7.4) and a temperature of 25 degrees C. The initial concentration of the alpha-keto acid anions was kept
