Glycineamide ribonucleotide transformylase has been purified 240-fold from chicken liver along with formyl-methenyl-methylenetetrahydrofolate synthetase (combined), through seven purification steps including a glycineamide ribonucleotide affinity column and a 10-formyl synthetase specific MgATP elution from hydroxylapatite. The transformylase is a homodimer of Mr 63,000 whereas the synthetase (combined) is composed of two identical subunits of Mr 83,000. Transformylase has been isolated free of the synthetase (combined) by an additional anion exchange chromatographic step resulting in a net 400-fold purification.
