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:0000256|HAMAP-Rule:MF_02121}.
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 Evidence={ECO:0000256|ARBA:ARBA00001636, ECO:0000256|HAMAP-
CC Rule:MF_02121};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 2/4.
CC {ECO:0000256|ARBA:ARBA00005076, ECO:0000256|HAMAP-Rule:MF_02121}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; L-homoserine from L-aspartate: step 2/3.
CC {ECO:0000256|ARBA:ARBA00005021, ECO:0000256|HAMAP-Rule:MF_02121}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 2/5. {ECO:0000256|ARBA:ARBA00005097,
CC ECO:0000256|HAMAP-Rule:MF_02121}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_02121}.
CC -!- SIMILARITY: Belongs to the aspartate-semialdehyde dehydrogenase family.
CC {ECO:0000256|ARBA:ARBA00010584, ECO:0000256|HAMAP-Rule:MF_02121}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02121}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
