During development of a novel method for constructing a series of deletions in Bacillus subtilis using an isogenic set of gene-disrupted mutants created by integration of pMutin, deletion of the trnS operon, consisting of seven tRNA genes, was found to affect cell growth, development of competence and spore formation. A suppressor (sts1) of the DeltatrnS mutant was isolated, sequenced and found to have undergone a single base change, CAG to GAG, in the first anticodon of tRNA(Leu), in the trnB operon.
