Summary
PurE was previously thought to be the catalytic subunit of phosphoribosylaminoimidazole carboxylase, with ATPase subunit PurK (Tiedeman, 1989). [More information is available at EcoGene: EG10793]. PurK and PurE were previously thought to be two subunits of AIR carboxylase , though more recent studies have shown the enzymes to be subunits of a distinct carboxylase and mutase, respectively . [More information is available at EcoCyc: EG10793].
