CC   -!- FUNCTION: Catalyzes the conversion of 4-hydroxy-
CC       tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.

CC         Rule:MF_00102, ECO:0000256|SAAS:SAAS01117970};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC       pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 4/4.
CC       {ECO:0000256|HAMAP-Rule:MF_00102, ECO:0000256|SAAS:SAAS01081412}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_00102}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00102,
CC       ECO:0000256|SAAS:SAAS01081435}.
CC   -!- SIMILARITY: Belongs to the DapB family. {ECO:0000256|HAMAP-
CC       Rule:MF_00102, ECO:0000256|SAAS:SAAS01081404}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC       of feature annotation. {ECO:0000256|HAMAP-Rule:MF_00102}.
CC   -!- CAUTION: The sequence shown here is derived from an
CC       EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is
CC       preliminary data. {ECO:0000313|EMBL:GAN58683.1}.
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:0000256|HAMAP-Rule:MF_00102}.
