In vitro L- and D-isomers of serine are also degraded, though slowly; it is the only serine dehydratase which can eliminate an amino group at the beta-carbon position. In vivo L-, D- and a mixure of DL-DAP allow growth. DL-DAP is toxic in the absence of this enzyme, it may inhibit enzymes involved in the synthesis of pyruvate and aspartate, as well as amino acids derived from them. | 0.903 |

The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia.
