| Comments |
The reaction can be divided into three consecutive steps: Schiff base formation with pyruvate, the addition of?L-aspartate-semialdehyde, and finally transimination leading to cyclization with simultaneous dissociation of the product. The product of the enzyme was initially thought to be (S)-2,3-dihydrodipicolinate [1,2], and the enzyme was classified accordingly as EC?4.2.1.52, dihydrodipicolinate synthase. Later studies of the enzyme from the bacterium?Escherichia coli?have suggested that the actual product of the enzyme is (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate [3], and thus the enzyme has been reclassified as 4-hydroxy-tetrahydrodipicolinate synthase. However, the identity of the product is still controversial, as more recently it has been suggested that it may be (S)-2,3-dihydrodipicolinate after all [5]. |
