Molecular biology

A single or two-strand bacterial RNA with both tRNA and mRNA functions. As part of a ribonucleoprotein complex it can rescue a ribosome that has become trapped in a complex by a mRNA that has lost ...

Pseudo-first order

Biology; Biochemistry

In kinetics, descriptive of a rate that is directly dependent upon the concentration of one reactant that is experimentally varied. The rate may also be dependent upon the fixed concentrations of ...

Sequence

Biology; Biochemistry

The ordered linear array of amino acid residues in a protein, of bases in a polynucleotide, or of glycosides in a complex polysaccharide; also, as a verb, to determine such a sequence, e.g. to ...

Triplex-forming oligonucleotide (TFO)

Biology; Biochemistry

An oligonucleotide that recognises a specific dsDNA sequence. Designed to affect the expression of a specific gene, it lies in the major groove of the double helix and forms Hoogstein base pairs with ...

Dirigent

Biology; Biochemistry

A protein, itself devoid of catalytic activity, taht directs the regio- and stereo-selective course of an enzymic reaction, e.g. the exclusive synthesis by an oxidase of (+)-pinoresinal from two ...

Rotational catalysis

Biology; Biochemistry

A proposed partial mechanism of ATP synthase in which a transmembrane ion channel, which is a hexamer composed of a ring of alternating and subunits, in which a single subunit rotates, binding ADP ...

Glypiated

Biology; Biochemistry

Descriptive of a glycosylphosphatidylinositol (GPI)-anchored protein, i.e. one that is associated with a cell membrane through an attached GPI group. An alternative term is piglylated, from ...
