Trypsin sensitivity of unflavinated His6-DMGDH H109R. Purified His6-DMGDH H109R (10 μmol/L) with or without bound-FAD was incubated with 0.5 μmol/L trypsin at 37°C for 0 or 240 min. Reactions were stopped by the rapid addition of gel-loading buffer and boiling of the samples. Samples were separated by SDS-PAGE and stained with Coomassie blue dye
