MetaCyc Protein: citrate lyase [acyl carrier protein] component

Gene: citD Accession Numbers: G6343 (MetaCyc), b0617, ECK0610

Synonyms: ybdX, CitD acyl carrier protein

Species: Escherichia coli K-12 substr. MG1655

Component of: citrate lyase, inactive

Subunit composition of citrate lyase [acyl carrier protein] component = [CitD]6
         citrate lyase, acyl carrier γ subunit = CitD

Alternative forms of citrate lyase, inactive: citrate lyase (extended summary available)

Summary:
This component of the citrate lyase is made of 6 copies of the γ subunit, a specialized acyl carrier protein (acp). In the original purification of the enzyme, this subunit was purified with a contaminant and the complex structure was thought to be α-6 β-6 γ-1 [Nilekani83]. Subsequent work identified the contaminant, and the structure was recognized as α-6 β-6 γ-6 [Quentmeier87].

The [acp] subunit is activated by the covalent binding of an unusual prosthetic group, 2'-(5''-phosphoribosyl)-3'-dephospho-CoA, which is synthesized from the precursor 2'-(5''-triphospho-α-D-ribosyl)-3'-dephospho-CoA [Schneider00a, Schneider00b] (see citrate lyase activation).
