Purification and Characterization of γ-Glutamylmethylamide Synthetase from Methylophaga sp. AA-30

γ-Glutamylmethylamide synthetase was purified about 70-fold from a cell-free extract of Methylophaga sp.AA-30 by ammonium sulfate fractionation, Octyl-Sepharose column chromatography, and Sephacryl S-300 gel filtration.Only a single protein band was detected after SDS-polyacrylamide gel electrophoresis of the purified preparation; the band was at a position corresponding to a molecular weight of 56,000.The molecular weight of the enzyme was calculated to be 440,000 by Superose 6HR gel filtration, so we suggest that the enzyme is an octomer of identical subunits.The enzyme had maximum activity at pH 7.5 and 40 deg C.It could use ethylamine and propylamine instead of methylamine as the substrate, but it could not use D-glutamate or L-glutamine instead of L-glutamate.
