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.
