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