RC STRAIN=MC0-3; RA Copeland A., Lucas S., Lapidus A., Barry K., Bruce D., Goodwin L., RA Glavina del Rio T., Dalin E., Tice H., Pitluck S., Chain P., RA Malfatti S., Shin M., Vergez L., Schmutz J., Larimer F., Land M., RA Hauser L., Kyrpides N., Mikhailova N., Tiedje J., Richardson P.; RT "Complete sequence of chromosome 1 of Burkholderia cenocepacia MC0- RT 3."; RL Submitted (FEB-2008) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the conversion of 4-hydroxy- CC tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate (By CC similarity). CC -!- CATALYTIC ACTIVITY: (S)-2,3,4,5-tetrahydropyridine-2,6- CC dicarboxylate + NAD(P)(+) + H(2)O = (2S,4S)-4-hydroxy-2,3,4,5- CC tetrahydrodipicolinate + NAD(P)H + H(+). CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 4/4. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the DapB family. 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 (PubMed:20503968) that the substrate of the CC enzymatic reaction is not dihydrodipicolinate (DHDP) but in fact CC (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid (HTPA), the CC product released by the DapA-catalyzed reaction.
