CC -!- FUNCTION: Catalyzes reversively the conversion of L-aspartate beta-
CC semialdehyde (ASA) to L-2,4-diaminobutyrate (DABA) by transamination
CC with L-glutamate. {ECO:0000256|RuleBase:RU365034}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-oxoglutarate + L-2,4-diaminobutanoate = L-aspartate 4-
CC semialdehyde + L-glutamate; Xref=Rhea:RHEA:11160, ChEBI:CHEBI:16810,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58761, ChEBI:CHEBI:537519;
CC EC=2.6.1.76; Evidence={ECO:0000256|RuleBase:RU365034};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|RuleBase:RU365034};
CC -!- PATHWAY: Amine and polyamine biosynthesis; ectoine biosynthesis; L-
CC ectoine from L-aspartate 4-semialdehyde: step 1/3.
CC {ECO:0000256|RuleBase:RU365034}.
CC -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC aminotransferase family. {ECO:0000256|RuleBase:RU003560}.
