Abstract

Aminoimidazole ribonucleotide (AIR) synthetase has been purified 15-fold to apparent ho-mogeneity from Escherichia coli which contains a multicopy plasmid containing the purM, AIR synthetase, gene. The protein is a dimer composed of two identical subunits of M_r38 500. The N-terminal sequence, amino acid composition, and steady-state kinetics of the protein have been determined. AIR synthetase has been shown to catalyze the transfer of the formyl oxygen of [¹⁸0]formylglycinamide ribonucleotide to P_i.
