Biochemistry

In analytical ultracentrifugation, one of the factors that determine a macromolecule's rate of sedimentation; (1-ur), where u is the partial specific volume of the macromolecule (expressed as ml/g) ...

Immunoaffinity chromatography

Biology; Biochemistry

A variant of affinity chromatography in which an antibody coupled to the stationary phase adsorbs an antigen which is subsequently eluted at a different pH or a higher salt concentration. Specific ...

Hierarchical condensation

Biology; Biochemistry

The hypothesis that, during the folding of a protein in solution, some regions are much more likely to adopt a secondary structure and that, once formed, these interact to direct the subsequent ...

Intermediary metabolism

Biology; Biochemistry

The individual enzymic reactions that in a tissue or inside a cell transform one metabolite into another, e.g. the conversion of lactate into glucose by the liver, the conversion of leucine into ...

Inhibitor of apoptosis

Biology; Biochemistry

Inhibitor of apoptosis (IAP) proteins are present in most animal cells and regulate the sensitivity of an animal cell to apoptosis-inducing stimuli by binding to and inhibiting activated caspases, ...

Right-handed helix

Biology; Biochemistry

By analogy with the right hand, a helix, e.g. of a polypeptide, that advances towards the C-terminus in the direction of the extended thumb as the backbone of a chain turns in the direction of the ...

Enhanceosome

Biology; Biochemistry

A highly-ordered cluster of tissue-specific transcription factors that assemble at regulatory elements of a eukaryotic gene and which, by their arrangement in space, act synergistically and ...
