Determination of relative promoter activities via β-galactosidase expression (measured in Miller units).
Strains | NC | NP1 | NP2 | ND1P1 | ND1P2 | ND2P1 | ND2P2 |
---|---|---|---|---|---|---|---|
MMB + glucose | 8.37 | 151.30 | 15.89 | 8.09 | 9.45 | 196.37 | 8.19 |
MMB + naphthalene | 8.30 | 199.31 | 11.52 | 11.87 | 9.94 | 297.38 | 11.54 |
*The β-galactosidase activity was determined in the following strains: NC (ND6 containing pDN19lacΩ); NP1 (ND6 containing pDN19lacΩ + catI promoter); NP2 (ND6 containing pDN19lacΩ + catII promoter); ND1P1 (ND6-ΔcatRI containing pDN19lacΩ + catI promoter); ND1P2 (ND6-ΔcatRI containing pDN19lacΩ + catII promoter); ND2P1 (ND6-ΔcatRII containing pDN19lacΩ + catI promoter); ND2P2 (ND6-ΔcatRII containing pDN19lacΩ + catII promoter).
