CC -!- FUNCTION: Catalyzes the NADPH-dependent formation of L-aspartate-
CC semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl-
CC 4-phosphate. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-aspartate 4-semialdehyde + NADP(+) + phosphate = 4-phospho-
CC L-aspartate + H(+) + NADPH; Xref=Rhea:RHEA:24284, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57535, ChEBI:CHEBI:57783,
CC ChEBI:CHEBI:58349, ChEBI:CHEBI:537519; EC=1.2.1.11;
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 2/4.
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; L-homoserine from L-aspartate: step 2/3.
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 2/5.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the aspartate-semialdehyde dehydrogenase family.
CC {ECO:0000305}.
