CC -!- FUNCTION: Involved in the synthesis of meso-diaminopimelate (m-DAP or
CC DL-DAP), required for both lysine and peptidoglycan biosynthesis.
CC Catalyzes the direct conversion of tetrahydrodipicolinate to LL-
CC diaminopimelate. {ECO:0000255|HAMAP-Rule:MF_01642}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,6S)-2,6-diaminoheptanedioate + 2-oxoglutarate = (S)-
CC 2,3,4,5-tetrahydrodipicolinate + H(+) + H2O + L-glutamate;
CC Xref=Rhea:RHEA:23988, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16810, ChEBI:CHEBI:16845, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:57609; EC=2.6.1.83; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01642};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01642};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate
CC (aminotransferase route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_01642}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01642}.
CC -!- SIMILARITY: Belongs to the class-I pyridoxal-phosphate-dependent
CC aminotransferase family. LL-diaminopimelate aminotransferase subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01642}.
