Asparagine

Asparagine (symbol Asn or N) is an α-amino acid that is used in the biosynthesis of proteins.

See Queuosine and Asparagine

Aspartic acid

Aspartic acid (symbol Asp or D; the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins.

See Queuosine and Aspartic acid

Bacteria

Bacteria (bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell.

See Queuosine and Bacteria

Escherichia coli

Eukaryote

The eukaryotes constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus.

See Queuosine and Eukaryote

Gene

In biology, the word gene has two meanings.

See Queuosine and Gene

Guanosine

Guanosine (symbol G or Guo) is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Queuosine and Guanosine are Hydroxymethyl compounds and nucleosides.

See Queuosine and Guanosine

Guanosine triphosphate

Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate.

See Queuosine and Guanosine triphosphate

Histidine

Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins.

See Queuosine and Histidine

Nucleoside

Nucleosides are glycosylamines that can be thought of as nucleotides without a phosphate group. Queuosine and Nucleoside are nucleosides.

See Queuosine and Nucleoside

Nucleotide base

Nucleotide bases (also nucleobases, nitrogenous bases) are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids.

See Queuosine and Nucleotide base

PreQ1 riboswitch

The PreQ1-I riboswitch is a cis-acting element identified in bacteria which regulates expression of genes involved in biosynthesis of the nucleoside queuosine (Q) from GTP.

See Queuosine and PreQ1 riboswitch

PreQ1-II riboswitch

PreQ1-II riboswitches form a class of riboswitches that specifically bind pre-queuosine1 (PreQ1), a precursor of the modified nucleoside queuosine.

See Queuosine and PreQ1-II riboswitch

PreQ1-III riboswitch

PreQ1-III riboswitches are a class of riboswitches that bind pre-queuosine1 (PreQ1), a precursor to the modified nucleoside queuosine.

See Queuosine and PreQ1-III riboswitch

Queuine

Queuine (Q) is a hypermodified nucleobase found in the first (or wobble) position of the anticodon of tRNAs specific for Asn, Asp, His, and Tyr, in most eukaryotes and prokaryotes. Queuosine and Queuine are Cyclopentenes.

See Queuosine and Queuine

Riboswitch

In molecular biology, a riboswitch is a regulatory segment of a messenger RNA molecule that binds a small molecule, resulting in a change in production of the proteins encoded by the mRNA.

See Queuosine and Riboswitch

Transfer RNA

Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins.

See Queuosine and Transfer RNA

Translation (biology)

In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates.

See Queuosine and Translation (biology)

Tyrosine

-Tyrosine or tyrosine (symbol Tyr or Y) or 4-hydroxyphenylalanine is one of the 20 standard amino acids that are used by cells to synthesize proteins.

See Queuosine and Tyrosine

Wobble base pair

A wobble base pair is a pairing between two nucleotides in RNA molecules that does not follow Watson-Crick base pair rules.

See Queuosine and Wobble base pair
