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.

Similar proteinsi

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.
