Zusammenfassung
The neomycin phosphotransferase gene (neo) from Transposon Tn5 is active in Gram-negative bacteria but silent in B. subtilis since it lacks an appropriate ribosome binding site for Gram-positive bacteria. Neo translation could be reactivated by coupling its initiation to the translational termination of the highly expressed beta-lactamase gene (penP) from B. licheniformis. This initiation occurred at the authentic neo start codon. Its efficiency was independent of the nucleotide sequence 5 to the neo gene, but strongly affected by the distance between the termination and initiation codon. It was the highest if both codons overlapped in the sequence ATGA. In B. licheniformis, a translationally coupled neo gene was inducible expressed as the penP gene demonstrating the potential of the technique to monitor the activity of expression units for which no direct assays exists.
