General annotation (Comments)

Function

Catalyzes the NADPH-dependent formation of L-aspartate-semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl-4-phosphate By similarity. HAMAP MF_02121

Catalytic activity

L-aspartate 4-semialdehyde + phosphate + NADP+ = L-4-aspartyl phosphate + NADPH. HAMAP MF_02121

Pathway

Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 2/4. HAMAP MF_02121

Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-homoserine from L-aspartate: step 2/3. HAMAP MF_02121

Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine from L-aspartate: step 2/5. HAMAP MF_02121

Subunit structure

Homodimer By similarity. HAMAP MF_02121

Sequence similarities

Belongs to the aspartate-semialdehyde dehydrogenase family.
