Where can I find the rRNA sequence of E.coli?
1 answer
Hi, may I first refer you to the Wikipedia article on ribosomal RNA: https://en.wikipedia.org/wiki/Ribosomal_RNA
This will explain the following facts in detail
- there is no singular "the complete rRNA" sequence
- instead there are three rRNA sequence species: 16S, 5S, and 23S
- these, together with proteins form the two ribosomal subunits: SSU and LSU
- multiple genes may encode the 3 RNA species
In addition there are many different e. coli strains. Here is an example query for the 5S gene in e. coli K12 substr. MG1655 Here is the corresponding Refseq sequence: https://www.ncbi.nlm.nih.gov/nuccore/NR_103249.1
Here is a query for all E. coli 5S rRNA sequences from RefSeq to enter in NCBI nucleotide search or use with Entrez e-utils:
"Escherichia coli"[organism] AND "5S ribosomal RNA" AND srcdb_refseq[PROP]

There are several ribosomal RNAs, 5S, 16S and 23S rRNAs. To find them search or blast across the E. coli genome, e.g., in NCBI: https://www.ncbi.nlm.nih.gov/assembly/GCF_000005845.2
