Organism
Staphylococcus epidermidis (strain ATCC 12228)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the formation of acetyl phosphate from acetate and ATP. Can also catalyze the reverse reaction.UniRule annotation

Catalytic activityi

ATP + acetate = ADP + acetyl phosphate.UniRule annotation

Cofactori

Mg2+UniRule annotation, Mn2+UniRule annotationNote: Mg2+. Can also accept Mn2+.UniRule annotation

Pathwayi: acetyl-CoA biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes acetyl-CoA from acetate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Acetate kinase (ackA)
  2. Phosphate acetyltransferase (pta)
This subpathway is part of the pathway acetyl-CoA biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes acetyl-CoA from acetate, the pathway acetyl-CoA biosynthesis and in Metabolic intermediate biosynthesis.
