Molecular biology

In metabolic studies, the exposure of a biological system (e.g. a tissue slice, a cell culture, mitochondria) to a radiolabelled metabolite over a relatively long time so as to establish a constant ...

Host-guest protocol

Biology; Biochemistry

An experiment designed to evaluate the contribution of different amino acids at a single sequence position to the stability of a polypeptide. Site-directed mutagenesis or synthetic chemical ...

Purine

Biology; Biochemistry

One of the two classes of heterocyclic organic bases that are found in nucleic acids (principally adenine and guanine) and in several other kinds of biological compounds, e.g. coenzymes, nucleotides, ...

Transamination

Biology; Biochemistry

The concurrent amination and reduction of a carbonyl of one compound as another is deaminated and oxidized; especially the conversion of one α-amino acid into its corresponding α-oxo acid as another ...

Furanose

Biology; Biochemistry

The form of a sugar when it is condensed into a 5-membered ring. By analogy with furane, the 5-membered cyclic compound containing an oxygen atom and two conjugated carbon-carbon double bonds, a ...

Enhancer

Biology; Biochemistry

A 50 to 1500 bp dsDNA segment that up-regulates transcription of a gene. The enhancer may be up- or downstream or even within an intron of the gene. It is distinct from the promoter; its action may ...

Pyrimidine

Biology; Biochemistry

One of the two classes of heterocyclic organic bases that are found in nucleic acids (principally uracil and cytosine in RNA; uracil and thymine in DNA) and in several other kinds of biological ...
