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   -!- 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         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.
CC       {ECO:0000305}.
