Functioni

Catalytic activityi

ATP + L-aspartate = ADP + 4-phospho-L-aspartate.

Pathwayi: L-lysine biosynthesis via DAP pathway

This protein is involved in step 1 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. Probable aspartokinase (MJ0571)
  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.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-tetrahydrodipicolinate from L-aspartate, the pathway L-lysine biosynthesis via DAP pathway and in Amino-acid biosynthesis.

Pathwayi: L-methionine biosynthesis via de novo pathway

This protein is involved in step 1 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. Probable aspartokinase (MJ0571)
  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 1 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. Probable aspartokinase (MJ0571)
  2. Aspartate-semialdehyde dehydrogenase (asd)
  3. Homoserine dehydrogenase (hom)

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
