The rrn DB is a curated database that catalogs the numbers of genes that encode for 16S and 23S ribosomal RNAs in Bacteria and Archaea. Typically, a single copy of each of these genes …

In bacteria and archaea, the ribosomal RNA operon (rrn) typically codes for the 16S, 23S and 5S rRNAs. Together with a suite of proteins, these form ribosomes—the molecular machines …

2014年11月20日 · With these changes, the rrnDB is better positioned to remain a comprehensive resource under the torrent of microbial genome sequencing. The enhanced rrn DB will …

2015年1月1日 · In bacteria and archaea, the ribosomal RNA operon (rrn) typically codes for the 16S, 23S and 5S rRNAs. Together with a suite of proteins, these form ribosomes—the …

2018年6月8日 · We review the number and location of the rRNA operons and discuss evolution of 16S rRNA (rrs) genes -which are considered as ultimate chronometers for phylogenetic …

2016年9月12日 · Genome-wide patterns of orthologous gene content covary with rrn copy number, suggesting convergent evolution in response to resource availability. Our findings …

2023年2月2日 · Recent studies have elucidated mechanisms underlying the integrity of ribosomal DNA and regulation of its transcription, including epigenetic mechanisms and a unique …

The redesigned rrnDB (http://rrndb.umms.med.umich.edu/) brings a substantial increase in the number of genomes described, improved curation, mapping of genomes to both NCBI and …
