Fig. 6From: Serial deletion reveals structural basis and stability for the core enzyme activity of human glutaminase 1 isoforms: relevance to excitotoxic neurodegenerationStability of enzyme activity for the dual N- and C-terminal deletion mutant and full-length GAC and KGA. a) Dual N- and C-terminal deletion mutant and full-length GAC and KGA were kept at 4 °C and glutaminase was determined every three days by the enzyme activity assay. b) Dual N- and C-terminal deletion mutant were lysed and subjected to Western blotting with a specific His-Tag antibody protein detectionBack to article page
