摘要
We constructed a new Thermus thermophilus cloning vector which enables the colour selection of cloned DNA inserts in the T. thermophilus HB27 host strain (beta-gal(-)) on growth plates containing 3,4-cyclohexenoesculetin beta-d-galactopyranoside (S-gal) in the medium. This vector harbors a modified beta-galactosidase gene (TTP0042 of T. thermophilus HB27) with 12 unique restriction enzyme sites (Acc65I, AvrII, BlpI, BssHII, EcoRI, EcoRV, HindIII, NruI, SalI, SpeI, SphI and XbaI) as multiple cloning sites under the control of the T. thermophilus slpA promoter. This host-vector system facilitates cloning procedures in T. thermophilus HB27.
