Escherichia coli K-12 substr. MG1655 Enzyme: ATP phosphoribosyltransferase

Gene: hisG Accession Numbers: EG10449 (EcoCyc), b2019, ECK2014

Regulation summary diagram for hisG

Subunit composition of ATP phosphoribosyltransferase = [HisG]2

ATP phosphoribosyltransferase (HisG) catalyzes the first step in the pathway of histidine biosynthesis.

HisG synthesizes phosphoribosyl-ATP via a displacement of the first carbon of 5-phosphoribosyl 1-pyrophosphate by the first nitrogen on the purine ring of ATP [Tebar76, Kronenberg75, Kleeman75].

ATP phosphoribosyltransferase functions as a dimer [Tebar78]. Interaction with histidine induces formation of a catalytically inactive hexamer. In this hexameric state, the active site is unavailable. In constrast, AMP inhibits HisG function by binding in the 5-phosphoribosyl 1-pyrophosphate site and occluding the ATP binding site [DallLarsen76, Lohkamp04]. Crystal structures of HisG bound to AMP and bound to phosphoribosyl-ATP have been solved to 2.7 Å and 2.9 Å resolution, respectively [Lohkamp00, Lohkamp04]. The structure of HisG has also been studied via spin-label and EPR methods [Tebar77, Tebar77a].
