In this study, the purification and characterization of an unreported GAD from a novel strain of Enterococcus raffinosus TCCC11660 were investigated. The native GAD from E. raffinosus TCCC11660 was purified 32.3-fold with a recovery rate of 8.3%, using ultrafiltration and ammonium sulfate precipitation, followed by ion-exchange and size-exclusion chromatography. The apparent molecular weight of purified GAD, as determined by SDS-PAGE and size-exclusion chromatography was 55 and 110 kDa, respectively, suggesting that GAD exists as a dimer of identical subunits in solution. In the best sodium citrate buffer, metal ions of Mo⁶⁺ and Mg²⁺ had positive effects, while Cu²⁺, Fe²⁺, Zn²⁺ and Co²⁺ showed significant adverse effects on enzyme activity. The optimum pH and temperature of GAD were determined to be 4.6 and 45 °C, while the K _m and V _max values for the sole L-glutamate substrate were 5.26 and 3.45 μmol L^-1 min^-1, respectively.21:T476,Methyl methanesulfonate and ethyl methanesulfonate are potential genotoxic impurities in imatinib mesylate. In this work, a simple, sensitive, reliable, and fast gas chromatography with mass spectrometry method for the simultaneous determination of methyl methanesulfonate and ethyl methanesulfonate was developed and validated. Total analysis time was only 7 min. An n-hexane/water solution was used to dissolve samples, and then extracted-ion-chromatogram mode was used to quantify methyl methanesulfonate and ethyl methanesulfonate. Calibration curv
