Liberation of zinc-containing L31 (RpmE) from ribosomes by its paralogous gene product, YtiA, in Bacillus subtilis.
We have found that alternative localization of two types of L31 ribosomal protein, RpmE and YtiA, is controlled by the intracellular concentration of zinc in Bacillus subtilis. The detailedExpand

Ribosome dimerization is essential for the efficient regrowth of Bacillus subtilis.
Ribosome dimers are a translationally inactive form of ribosomes found in Escherichia coli and many other bacterial cells. In this study, we found that the 70S ribosomes of Bacillus subtilisExpand

Zinc is a key factor in controlling alternation of two types of L31 protein in the Bacillus subtilis ribosome
We have analysed changes in the composition of ribosomal proteins during cell growth in Bacillus subtilis. Ribosome fractions were prepared from B. subtilis cells at different phases of growth andExpand

A fail‐safe system for the ribosome under zinc‐limiting conditions in Bacillus subtilis
As zinc is an essential trace metal ion for all living cells, cells elaborate a variety of strategies to cope with zinc starvation. In Bacillus subtilis, genes encoding ribosomal proteins L31 and S14Expand

Multiple rRNA operons are essential for efficient cell growth and sporulation as well as outgrowth in Bacillus subtilis.
The number of copies of rRNA (rrn) operons in a bacterial genome differs greatly among bacterial species. Here we examined the phenotypic effects of variations in the number of copies of rRNA genesExpand

Bacillus subtilis mutants harbouring a single copy of the rRNA operon exhibit severe defects in growth and sporulation.
The number of copies of rRNA genes in bacterial genomes differs greatly among bacterial species. It is difficult to determine the functional significance of the heterogeneity of each rRNA operonExpand

Protein acetylation involved in streptomycin biosynthesis in Streptomyces griseus.
Protein acetylation, the reversible addition of an acetyl group to lysine residues, is a protein post-translational modification ubiquitous in living cells. Although the involvement of proteinExpand

Inactivation of ribosomal protein genes in Bacillus subtilis reveals importance of each ribosomal protein for cell proliferation and cell differentiation.
Among the 57 genes that encode ribosomal proteins in the genome of Bacillus subtilis, a Gram-positive bacterium, 50 genes were targeted by systematic inactivation. Individual deletion mutants of 16Expand

Dynamic changes in the extracellular proteome caused by absence of a pleiotropic regulator AdpA in Streptomyces griseus
In Streptomyces griseus, A‐factor (2‐isocapryloyl‐3R‐hydroxymethyl‐γ‐butyrolactone) triggers morphological development and secondary metabolism by inducing a pleiotropic transcriptional regulatorExpand

Defect in the formation of 70S ribosomes caused by lack of ribosomal protein L34 can be suppressed by magnesium.
To elucidate the biological functions of the ribosomal protein L34, which is encoded by the rpmH gene, the rpmH deletion mutant of Bacillus subtilis and two suppressor mutants were characterized.Expand
