CC -!- FUNCTION: Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate CC (HTPA) to tetrahydrodipicolinate. {ECO:0000255|HAMAP-Rule:MF_00102}. CC -!- CATALYTIC ACTIVITY: CC Reaction=(S)-2,3,4,5-tetrahydrodipicolinate + H2O + NAD(+) = (2S,4S)-4- CC 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(+) = (2S,4S)- CC 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 reductase CC (DHDPR), catalyzing the conversion of dihydrodipicolinate to CC tetrahydrodipicolinate. However, it was shown in E.coli that the CC substrate of the enzymatic reaction is not dihydrodipicolinate (DHDP) CC but in fact (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid CC (HTPA), the product released by the DapA-catalyzed reaction.
