Catalyzes the formation of acetyl phosphate from acetate and ATP. Can also catalyze the reverse reaction. During anaerobic growth of the organism, this enzyme is also involved in the synthesis of most of the ATP formed catabolically.

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

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.
