Gene

metXA

Organism
Clavibacter michiganensis subsp. michiganensis (strain NCPPB 382)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Transfers an acetyl group from acetyl-CoA to L-homoserine, forming 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 (metXA)
This subpathway is part of the pathway L-methionine biosynthesis via de novo pathway, which is itself part of Amino-acid biosynthesis.
