Catalyzes the formation of 2-(5''-triphosphoribosyl)-3'-dephosphocoenzyme-A, the precursor of the prosthetic group of the holo-acyl carrier protein (gamma chain) of citrate lyase, from ATP and dephospho-CoA. 3'-dephospho-CoA + ATP = 2'-(5''-triphospho-alpha-D-ribosyl)-3'-dephospho-CoA + adenine Belongs to the CitG/MdcB family. This protein seems to consist of a CitG domain with an incomplete N-terminal CitX region. The start site is approximate as there is similarity downstream up to the C-terminal codon of the adjacent sodA gene.
