Revised Manuscript Received February 19, 1986 abstract: 5-Aminoimidazole ribonucleotide (AIR) synthetase, glycinamide ribonucleotide (GAR) synthetase, and GAR transformylase activities from chicken liver exist on a single polypeptide of Mr 110000 [Daubner, C. S., Schrimsher, J. L., Schendel, FJ, Young, M., Henikoff, S., Patterson, D., Stubbe, J., & Benkovic, S. J.(1985) Biochemistry 24, 7059-7062], Details of copurification of these three activities through four chromatographic steps are reported. The ratios of these activities remain constant throughout the purification. AIR synthetase has an absolute requirementfor K+ for activity and under these conditions has apparent molecular weights of 330000, determined by Sephadex G-200 chromatography, and 133 000, determined by sucrose density gradient ultracentrifugation. Incubation of lgO-labeled formylglycinamidine ribonucleotide (FGAM) with AIR synthetase results in stoichiometric production of AIR, ADP, and [180] Pj. NMR spectra of/3-FGAM and/3-AIR are reported.
