Citrate lyase ligase, also known as [Citrate (pro-3S)-lyase] ligase, is responsible for acetylation of the (2-(5''-phosphoribosyl)-3'-dephosphocoenzyme-A) prosthetic group of the gamma subunit of citrate lyase, converting the inactive thiol form of this enzyme to the active form. The acetylation of 1 molecule of deacetyl-citrate lyase to enzymatically active citrate lyase requires 6 molecules of ATP. The Adenylylyltranferase activity of the enzyme involves the formation of AMP and and pyrophosphate in the acetylation reaction.
