CitX

• PFAM accession number: PF03802
• Interpro abstract (IPR005551):

  Members of this protein family are annotated as CitX, containing the CitX domain, the domain is also found in the CitXG bifunctional protein, of the citrate lyase system. CitX transfers the prosthetic group 2'-(5''-triphosphoribosyl)-3'-dephospho-CoA to the citrate lyase gamma chain, an acyl carrier protein. This enzyme may be designated holo-ACP synthase, holo-citrate lyase synthase, or apo-citrate lyase phosphoribosyl-dephospho-CoA transferase. In a few genera, including Haemophilus, this protein occurs as a fusion protein with CitG ( EC 2.7.8.25 ), an enzyme involved in prosthetic group biosynthesis. This CitX family is easily separated from the holo-ACP synthases of other enzyme systems.

• GO process: prosthetic group biosynthetic process (GO:0051191)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry CitX
