Abstract excerpt
Nonsense suppressor strains of Lactococcus lactis were isolated using plasmids containing nonsense mutations or as revertants of a nonsense auxotrophic mutant. The nonsense suppressor gene was cloned from two suppressor strains and the DNA sequence determined. One suppressor is an ochre suppressor with an altered tRNA(gln) and the other an amber suppressor with an altered tRNA(ser). The nonsense suppressors...
