CC ChEBI:CHEBI:32551, ChEBI:CHEBI:57791; EC=4.1.1.20;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02120,
CC ECO:0000256|RuleBase:RU003738};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|HAMAP-Rule:MF_02120, ECO:0000256|PIRSR:PIRSR600183-50,
CC ECO:0000256|RuleBase:RU003738};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; L-lysine from DL-2,6-diaminopimelate: step 1/1.
CC {ECO:0000256|HAMAP-Rule:MF_02120, ECO:0000256|RuleBase:RU003738}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_02120}.
CC -!- SIMILARITY: Belongs to the Orn/Lys/Arg decarboxylase class-II family.
CC LysA subfamily. {ECO:0000256|HAMAP-Rule:MF_02120}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02120}.
