Comments [?]

FUNCTIONCatalyzes the NADPH-dependent formation of L-aspartate- semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl- 4-phosphate.
CATALYTIC ACTIVITY Reaction=L-aspartate 4-semialdehyde + phosphate + NADP(+) = 4-phospho- L-aspartate + NADPH + H(+); Xref=Rhea:RHEA:24284, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57535, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:537519; EC=1.2.1.11;
PATHWAYAmino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 2/4.
PATHWAYAmino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-homoserine from L-aspartate: step 2/3.
PATHWAYAmino-acid biosynthesis; L-threonine biosynthesis; L-threonine from L-aspartate: step 2/5.
SUBUNITHomodimer.
SIMILARITYBelongs to the aspartate-semialdehyde dehydrogenase family.
