Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate.By similarity

Catalytic activityi

ATP + L-homoserine = ADP + O-phospho-L-homoserine.

Pathway:iL-threonine biosynthesis

This protein is involved in step 4 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 (HOM32), Aspartokinase (HOM3), Aspartokinase (I503_03868)
  2. Aspartate-semialdehyde dehydrogenase (HOM2)
  3. Homoserine dehydrogenase (HOM6)
  4. Homoserine kinase (THR1)
  5. no protein annotated in this organism
This subpathway is part of the pathway L-threonine biosynthesis, 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 L-threonine from L-aspartate, the pathway L-threonine biosynthesis and in 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 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.
