Protein

Aspartate-semialdehyde dehydrogenase

Gene

asd

Organism
Streptococcus pneumoniae (strain ATCC BAA-255 / R6)
Status
Unreviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

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

Catalytic activityi

L-aspartate 4-semialdehyde + phosphate + NADP+ = L-4-aspartyl phosphate + NADPH.UniRule annotation

Pathwayi: L-lysine biosynthesis via DAP pathway

This protein is involved in step 2 of the subpathway that synthesizes (S)-tetrahydrodipicolinate from L-aspartate.UniRule annotation
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.UniRule annotation
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)

Pathwayi: L-threonine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-threonine from L-aspartate.UniRule annotation
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)
  5. no protein annotated in this organism
