Table 1.

Comparison of the specific activity of mEPSPS from various sources

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)
