Biochemistry

Ion-exchange chromatography

Biology; Biochemistry

A technique for separation of charged compounds or macromolecules in solution according to their affinities for a positively charged stationary phase (an anion exchanger) or a negatively charged ...

A metabolic reaction that recovers some of a partially degraded compound for resynthesis, e.g. resynthesis of GTP from guanine recovered from degradation of nucleotides via the hypoxanthine-guanine ...

Wobble

Biology; Biochemistry

The presumed slackness of structural requirements for complementarily in fitting codon to anticodon that permits several bases in the third position of the codon to pair with a particular base in the ...

Mass spectrographic immunoassay (MSIA)

Biology; Biochemistry

A technique for characterization of antigens, especially when more than one may bind to an antibody. After isolation of an antigen from a solution by using an immobilised antibody, the adsorbed ...

Half-chair conformation

Biology; Biochemistry

The conformation of a pyranose ring that has been strained to place four adjacent atoms in one plane, e.g. the postulated transition state of the N-acetylglucosamine residue during lysozyme ...

Multienzyme complex

Biology; Biochemistry

An aggregate of enzymes of specific composition and geometry that act in sequence on a substrate and that, although separable in vitro, fit and function together for efficiency, e.g. pyruvate ...

TATA box

Biology; Biochemistry

A consensus sequence of eukaryotic DNA, named for its sequence on the coding strand, that aligns RNA polymerase II with the start site, about 25 bp downstream from it; from it; also known as a ...
