Protein

Serine acetyltransferase

Gene

cysE

Organism
Buchnera aphidicola subsp. Schizaphis graminum (strain Sg)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalytic activityi

Acetyl-CoA + L-serine = CoA + O-acetyl-L-serine.

Pathwayi: L-cysteine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-cysteine from L-serine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Serine acetyltransferase (cysE)
  2. Cysteine synthase (cysK)
This subpathway is part of the pathway L-cysteine 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-cysteine from L-serine, the pathway L-cysteine biosynthesis and in Amino-acid biosynthesis.
