Organism
Burkholderia thailandensis (strain ATCC 700388 / DSM 13276 / CIP 106301 / E264)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Involved in the methionine biosynthesis. Catalyzes the transfer of the acetyl group from acetyl-CoA to the hydroxyl group of L-homoserine to yield O-acetyl-L-homoserine.UniRule annotation

Catalytic activityi

Acetyl-CoA + L-homoserine = CoA + O-acetyl-L-homoserine.UniRule annotation

Pathwayi: L-methionine biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes O-acetyl-L-homoserine from L-homoserine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Homoserine O-acetyltransferase (metX), Homoserine O-acetyltransferase (metX)
This subpathway is part of the pathway L-methionine biosynthesis via de novo pathway, 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.
