A bacterial strain producing an extracellular ß-amylase, designated KYJ 963, was isolated from Korean saltfermented anchovy (anchovy-jeot). A nearly complete nucleotide sequence of a 16S ribosomal RNA from the isolate was determined. On the basis of the results of 16S ribosomal DNA sequence, cellular fatty acid composition, sensitivity test to antibiotics and so on, the strain KYJ 963 was ident...

All ribosomal RNAs are preceded by leader sequences not present in the final ribosome particles. The highly conserved leader sequences of bacterial rRNAs are known to be important for the folding and assembly of functional ribosomes. Very likely transient binding of the leader to mature parts of the 16S RNA occurs during transcription. To better understand the mechanistic details of these funct...

RNA-protein cross-links were introduced into E. coli 30S ribosomal subunits by treatment with methyl p-azidopEenyl acetimidate. After partial nuclease digestion of the RNA moiety, a number of cross-linked RNA-protein complexes were isolated by a new three-step procedure. Protein and RNA analysis of the individual complexes gave the following results: Proteins S3, S4, S5 and S8 are cross-linked ...

BACKGROUND Prokaryotic ribosomal protein S8 is an important RNA-binding protein that occupies a central position within the small ribosomal subunit. It interacts extensively with 16S rRNA and is crucial for the correct folding of the central domain of the rRNA. S8 also controls the synthesis of several ribosomal proteins by binding to mRNA. It binds specifically to very similar sites in the two...

A bacterial strain, designated BzDS03 was isolated from water sample, collected from Dal Lake Srinagar. The strain was characterized by using 16S ribosomal RNA gene and 16S-23S rRNA internal transcribed spacer region sequences. Phylogenetic analysis showed that 16S rRNA sequence of the isolate formed a monophyletic clade with genera Escherichia. The closest phylogenetic relative was Escherichia...
