Molecular biology

regulatory subunit

Biology; Biochemistry

A part of a multimeric enzyme; a protein that binds to and inhibits the catalytic subunit unless it is bound to a regulating molecule; e.g. in the case of cyclic AMP-dependent protein kinase, the ...

A product of plant origin that converts hides into leather; often polyphenols and aldehydes that cross-link collagen chains and render them insoluble and unreactive to enzymes that would degrade and ...

expression cloning

Biology; Biochemistry

As part of a repetitive process for screening a library, the sampling of cells according to the presence of the product of the gene of interest, e.g. the identification of the glutamate receptor in a ...

long interspersed nuclear element (LINE)

Biology; Biochemistry

Retrotransposons, double-stranded DNA sequences, 6-7 kb long, that occur in families of thousands of nearly identical copies which have apparently been randomly inserted into the mammalian genome. ...

small G protein

Biology; Biochemistry

A class of proteins that effect intracellular structural changes via modifications of the cytoskeleton. Like other G proteins, they are active when bound to GTP, but inactive when the GTP is ...

nearest-neighbour analysis

Biology; Biochemistry

A method of analysis in which a polymer is first synthesized from a precursor labelled in a specific atom, then degraded in such a way that the labelled atom appears with the adjacent moiety and ...

extended X-ray absorption fine structure (EXAFS)

Biology; Biochemistry

A technique for investigation of the immediate environment of metal atoms in metalloprotein crystals or solutions, e.g. Fe-S bond distances in rubredoxin; the X-ray energy is varied and the fine ...
