CC -!- FUNCTION: Catalyzes the condensation of (S)-aspartate-beta-semialdehyde
CC [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
CC {ECO:0000256|ARBA:ARBA00003294, ECO:0000256|HAMAP-Rule:MF_00418}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-aspartate 4-semialdehyde + pyruvate = (2S,4S)-4-
CC hydroxy-2,3,4,5-tetrahydrodipicolinate + H(+) + H2O;
CC Xref=Rhea:RHEA:34171, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:67139, ChEBI:CHEBI:537519; EC=4.3.3.7;
CC Evidence={ECO:0000256|ARBA:ARBA00000594, ECO:0000256|HAMAP-
CC Rule:MF_00418};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 3/4.
CC {ECO:0000256|ARBA:ARBA00005120, ECO:0000256|HAMAP-Rule:MF_00418}.
CC -!- SUBUNIT: Homotetramer; dimer of dimers. {ECO:0000256|HAMAP-
CC Rule:MF_00418}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00418}.
CC -!- SIMILARITY: Belongs to the DapA family. {ECO:0000256|HAMAP-
CC Rule:MF_00418, ECO:0000256|PIRNR:PIRNR001365}.
CC -!- CAUTION: Was originally thought to be a dihydrodipicolinate synthase
CC (DHDPS), catalyzing the condensation of (S)-aspartate-beta-semialdehyde
CC [(S)-ASA] and pyruvate to dihydrodipicolinate (DHDP). However, it was
CC shown in E.coli that the product of the enzymatic reaction is not
CC dihydrodipicolinate but in fact (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-
CC dipicolinic acid (HTPA), and that the consecutive dehydration reaction
CC leading to DHDP is not spontaneous but catalyzed by DapB.
CC {ECO:0000256|HAMAP-Rule:MF_00418}.
