Table 1.
Sample | Mean specific activity (Units/mg mEPSPS) ± SD |
---|---|
Microbial mEPSPS | 6,700 ± 32 |
GA21 maize mEPSPS | 734 ± 16 |
Microbial mEPSPS + non-transgenic maize extract | 1,560 ± 21 |
One unit of mEPSPS activity is defined as the release of 1 nmol of phosphate per minute under standard assay conditions (Padgette et al. 1987)
