CC -!- FUNCTION: Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate
CC (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L-
CC lysine and an essential component of the bacterial peptidoglycan.
CC {ECO:0000255|HAMAP-Rule:MF_00197}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,6S)-2,6-diaminoheptanedioate = meso-2,6-
CC diaminoheptanedioate; Xref=Rhea:RHEA:15393, ChEBI:CHEBI:57609,
CC ChEBI:CHEBI:57791; EC=5.1.1.7; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00197};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; DL-2,6-diaminopimelate from LL-2,6-diaminopimelate: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00197}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00197}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00197}.
CC -!- SIMILARITY: Belongs to the diaminopimelate epimerase family.
CC {ECO:0000255|HAMAP-Rule:MF_00197}.
