Comments [?]

Function Catalyzes the NADPH-dependent formation of L-aspartate-semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl-4-phosphate.
Catalytic activity RHEA:24284: L-aspartate 4-semialdehyde + NADP(+) + phosphate = 4-phospho-L-aspartate + H(+) + NADPH
EC 1.2.1.11
Pathway Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 2/4.
Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-homoserine from L-aspartate: step 2/3.
Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine from L-aspartate: step 2/5.
Subunit Homodimer.
Similarity Belongs to the aspartate-semialdehyde dehydrogenase family.
