Functioni

Catalyzes the NADPH-dependent formation of L-aspartate-semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl-4-phosphate.1 Publication

Catalytic activityi

L-aspartate 4-semialdehyde + phosphate + NADP+ = L-4-aspartyl phosphate + NADPH.1 Publication

Kineticsi

  1. KM=0.12 mM for L-aspartate 4-semialdehyde1 Publication
  2. KM=0.13 mM for NADP+1 Publication
  3. KM=1.5 mM for phosphate1 Publication

    Pathwayi: L-lysine biosynthesis via DAP pathway

    This protein is involved in step 2 of the subpathway that synthesizes (S)-tetrahydrodipicolinate from L-aspartate.
    Proteins known to be involved in the 4 steps of the subpathway in this organism are:
    1. Aspartokinase (lysC)
    2. Aspartate-semialdehyde dehydrogenase (asd)
    3. 4-hydroxy-tetrahydrodipicolinate synthase (dapA)
    4. 4-hydroxy-tetrahydrodipicolinate reductase (dapB)
    This subpathway is part of the pathway L-lysine biosynthesis via DAP pathway, which is itself part of Amino-acid biosynthesis.

    Pathwayi: L-methionine biosynthesis via de novo pathway

    This protein is involved in step 2 of the subpathway that synthesizes L-homoserine from L-aspartate.
    Proteins known to be involved in the 3 steps of the subpathway in this organism are:
    1. Aspartokinase (lysC)
    2. Aspartate-semialdehyde dehydrogenase (asd)
    3. Homoserine dehydrogenase (hom)
    This subpathway is part of the pathway L-methionine biosynthesis via de novo pathway, which is itself part of Amino-acid biosynthesis.

    Pathwayi: L-threonine biosynthesis

    This protein is involved in step 2 of the subpathway that synthesizes L-threonine from L-aspartate.
    Proteins known to be involved in the 5 steps of the subpathway in this organism are:
    1. Aspartokinase (lysC)
    2. Aspartate-semialdehyde dehydrogenase (asd)
    3. Homoserine dehydrogenase (hom)
    4. Homoserine kinase (thrB)
