Apr, ampicillin resistance; Mevr, pravastatin resistance.

The pDrHj2 plasmid was constructed as follows. The sequence between SacI and KpnI in pUC119 was replaced with the mevinoline resistance gene, and the sequence between HindIII and XbaI was replaced with the gene of a halophilic β-galactosidase (bgaH) under the control of csg promoter. The bgaH gene was obtained from Haloferax alicantei and was oriented in the direction opposite that in which the mevinoline resistance gene was oriented. The csg promoter is from Haloarcula japonica. Ha. japonica has a large amount of a glycoprotein (cell surface glycoprotein [CSG]) on the cell surface, suggesting that the csg promoter is powerful.
