RT biosynthesis pathway in prokaryotes identifies a diverged form of LL-
RT diaminopimelate aminotransferase.";
RL J. Bacteriol. 190:3256-3263(2008).
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. Is also able to catalyze the reverse reaction in
CC vitro, i.e. the transamination of LL-diaminopimelate with 2-
CC oxoglutarate to produce tetrahydrodipicolinate and glutamate. Cannot
CC use m-DAP, lysine or ornithine as the amino-group donor, when using 2-
CC oxoglutarate as the amino-group acceptor. Cannot use pyruvate, indole
CC 3-pyruvate, oxaloacetate or phenyl pyruvate as the amino-group
CC acceptor, when using LL-DAP as the amino-group donor.
CC {ECO:0000269|PubMed:18310350}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,6S)-2,6-diaminoheptanedioate + 2-oxoglutarate = (S)-
CC 2,3,4,5-tetrahydrodipicolinate + H(+) + H2O + L-glutamate;

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01642};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=37 uM for LL-2,6-diaminopimelate {ECO:0000269|PubMed:18310350};
CC KM=14 uM for L-2,3,4,5-tetrahydrodipicolinate
CC {ECO:0000269|PubMed:18310350};
CC KM=0.40 mM for 2-oxoglutarate {ECO:0000269|PubMed:18310350};
CC KM=4.3 mM for glutamate {ECO:0000269|PubMed:18310350};
CC Vmax=10.6 umol/min/mg enzyme for the forward reaction
CC (tetrahydrodipicolinate synthesis) {ECO:0000269|PubMed:18310350};
CC Vmax=0.450 umol/min/mg enzyme for the reverse reaction (LL-DAP
CC synthesis) {ECO:0000269|PubMed:18310350};
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 ECO:0000269|PubMed:18310350}.
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}.
