A metal-rich intermediate was captured prior to metal formation by means of a substitution reaction during the disproportionation of a metastable Ga(I) bromide solution. In the thus obtained Ga(22) cluster (see structure), the central gallium atom displays the unusual coordination number of 13.
A gene library of Streptomyces lividans has been screened for tRNA-encoding genes with labeled Streptomyces tRNA as a probe. By sequence analysis of hybridizing fragments, two single genes have been identified which code for tRNA(Asp) and tRNA(Gly). Associated with the tRNA(Gly) gene, there are three open reading frames (ORFs) which might code for gene products possibly involved in active transport processes through the bacterial membrane. The transcriptional organization of tRNAGly and the following ORFs was examined by high-resolution S1 mapping. A third clone carried a cluster of genes which encode two tRNA(Gln) and three tRNA(Glu). This cluster corresponds to a similar cluster previously described for Streptomyces rimosus [Plohl and Gamulin, Mol. Gen. Genet. 222 (1990) 129-134].
Three clones containing rRNA genes have been isolated from a gene library of Streptomyces lividans. Two clones carried entire but different rRNA-operons. The third clone comprised the 3'-end of a 23S-rRNA gene, the entire 5S-rRNA gene and the spacer region between them. The nucleotide sequence starting within the 23S-rRNA gene beyond the putative transcription terminator downstream the 5S-rRNA gene has been determined (EMBL acc. no X58874).
