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   -!- 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}.
