Functioni

Catalytic activityi

L-homoserine + NAD(P)+ = L-aspartate 4-semialdehyde + NAD(P)H.

Pathwayi: L-methionine biosynthesis via de novo pathway

This protein is involved in step 3 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 (SPBC19F5.04)
  2. Probable aspartate-semialdehyde dehydrogenase (SPCC1827.06c)
  3. Probable homoserine dehydrogenase (SPBC776.03)
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 3 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 (SPBC19F5.04)
  2. Probable aspartate-semialdehyde dehydrogenase (SPCC1827.06c)
  3. Probable homoserine dehydrogenase (SPBC776.03)
  4. Probable homoserine kinase (SPBC4C3.03)
  5. Threonine synthase (thrc)
This subpathway is part of the pathway L-threonine biosynthesis, which is itself part of Amino-acid biosynthesis.

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.
