Caution

Was originally thought to be a dihydrodipicolinate synthase (DHDPS), catalyzing the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to dihydrodipicolinate (DHDP). However, it was shown in E.coli that the product of the enzymatic reaction is not dihydrodipicolinate but in fact (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinic acid (HTPA), and that the consecutive dehydration reaction leading to DHDP is not spontaneous but catalyzed by DapB.
