Function
function
Catalyzes the NADPH-dependent formation of L-aspartate-semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl-4-phosphate.
Catalytic activity
- L-aspartate 4-semialdehyde + phosphate + NADP+ = 4-phospho-L-aspartate + NADPH + H+
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.
