- ND no activity detected. (Relative activity compared to d-erythrose). The values provided are the means of three independent replicates; the standard deviations represented less than 10% of the means
- aActivity determined in 50 mM phosphate buffer at its optimal pH (pH 6 for ER10, and pH 4 for ER25)
- bActivity determined in 50 mM phosphate buffer with high osmotic condition (200 g/L glucose) at its optimal pH
