What does the SSU rRNA do?

What does the SSU rRNA do?

Small subunit ribosomal ribonucleic acid (SSU rRNA) is the smaller of the two major RNA components of the ribosome. Associated with a number of ribosomal proteins, the SSU rRNA forms the small subunit of the ribosome. It is encoded by SSU-rDNA….

Is SSU rRNA the same as 16S rRNA?

Small subunit (=SSU) rRNA is called differently for the different domains. For Bacteria and Archaea (Prokaryotes), it is called 16S rRNA. For Eukarya (Eukaryotes), it is called 18S rRNA. Please note that SSU rRNA of mitochondrion and plastid (chloroplast) is also called 16S rRNA.

What is the role of the 16S rRNA in the ribosome?

The 16S rRNA is the central structural component of the bacterial and archaeal 30S ribosomal subunit and is required for the initiation of protein synthesis and the stabilization of correct codon-anticodon pairing in the A site of the ribosome during mRNA translation [1].

What is SSU sequencing?

Overview. SSU-ALIGN is a software package for identifying, aligning, masking and visualizing archaeal 16S, bacterial 16S and eukaryotic 18S small subunit ribosomal RNA (SSU rRNA) sequences.

What is SSU gene?

The small subunit ribosomal RNA (SSU rRNA) gene is the most widely used molecular taxonomic marker for microorganisms (16S rRNA for Bacteria and Archaea, and 18S rRNA for Eukaryota). This is primarily because of its universality, sequence variation and data availability from organisms across the tree of life.

What is the SSU rRNA gene?

What is Ribotyping used for?

Ribotyping is a molecular technique for bacterial identification and characterization that uses information from rRNA-based phylogenetic analyses. It is a rapid and specific method widely used in clinical diagnostics and analysis of microbial communities in food, water, and beverages.

Why is 16S rRNA used for taxonomic classification?

Compared to taxonomy classification using only a limited variable region of the 16S rRNA gene, sFL16S provides high quality base-resolution and accurately classifies species and sometimes potential strain levels by reducing false positives.

Why is it called 16S?

16S rRNA stands for 16S ribosomal ribonucleic acid (rRNA), where S (Svedberg) is a unit of measurement (sedimentation rate). This rRNA is an important constituent of the small subunit (SSU) of prokaryotic ribosomes as well as mitochondria and chloroplasts.

How many variable regions are there in SSU rRNA?

The bacterial 16S gene contains nine hypervariable regions (V1–V9), ranging from about 30 to 100 base pairs long, that are involved in the secondary structure of the small ribosomal subunit.
