CC -!- FUNCTION: Catalyzes the conversion of 4-hydroxy- CC tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate. CC {ECO:0000255|HAMAP-Rule:MF_00102}. CC -!- CATALYTIC ACTIVITY: CC Reaction=(S)-2,3,4,5-tetrahydrodipicolinate + H2O + NAD(+) = CC (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate + H(+) + NADH; CC Xref=Rhea:RHEA:35323, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:16845, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, CC ChEBI:CHEBI:67139; EC=1.17.1.8; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00102}; CC -!- CATALYTIC ACTIVITY: CC Reaction=(S)-2,3,4,5-tetrahydrodipicolinate + H2O + NADP(+) = CC (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate + H(+) + NADPH; CC Xref=Rhea:RHEA:35331, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:16845, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, CC ChEBI:CHEBI:67139; EC=1.17.1.8; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00102}; CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 4/4. CC {ECO:0000255|HAMAP-Rule:MF_00102}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00102}. CC -!- SIMILARITY: Belongs to the DapB family. {ECO:0000255|HAMAP- CC Rule:MF_00102}. CC -!- CAUTION: Was originally thought to be a dihydrodipicolinate CC reductase (DHDPR), catalyzing the conversion of CC dihydrodipicolinate to tetrahydrodipicolinate. However, it was CC shown in E.coli that the substrate of the enzymatic reaction is CC not dihydrodipicolinate (DHDP) but in fact (2S,4S)-4-hydroxy- CC 2,3,4,5-tetrahydrodipicolinic acid (HTPA), the product released by CC the DapA-catalyzed reaction. {ECO:0000305}.
