Overexpression of membrane-bound 1-phosphatase in R. etli CE3 or S. meliloti 1021 harboring pMJK-1
| Strain | Specific activity |
|---|---|
| nmol/min/mg | |
| R. etli CE3 | 0.002 |
| R. leguminosarum 3841 | 0.014 |
| R. etli CE3/pMJK-1 | 0.098 |
| S. meliloti 1021 | NDa |
| S. meliloti 1021/pLAFR-1 | ND |
| S. meliloti 1021/pMJK-1 | 0.059 |
ND, no detectable phosphatase activity is present in membranes. The specific activity of the 1-phosphatase was measured using washed membranes from the indicated strains of Rhizobium.
