Molecular biology

A proposed model for chaperone-assisted protein folding in which a chaperone, GroEL for instance, provides an environment in which a denatured protein can unfold and correctly refold, undisturbed by ...

Traffic ATPase

Biology; Biochemistry

A class of transmembrane transporters that includes the cystic fibrosis transmembrane regulator (CFTR) and transporters responsible for multidrug resistance. Transport is coupled to ATP hydrolysis ...

Layer line

Biology; Biochemistry

A feature of an X-ray diffraction pattern of a fibre. For fibres that contain aligned helices, the reflections appear as a pattern of spots arrayed in lines perpendicular to the fibre axis and the ...

Medium-chain fatty acid

Biology; Biochemistry

A fatty acid with a skeleton of 4-12 carbon atoms. Those with fewer carbon atoms are short-chain fatty acids; those with more (up to 20 carbon atoms) are long-chain fatty acids; and those with ...

Omega (Ω)-loop

Biology; Biochemistry

An irregular secondary structure on the surface of many globular proteins that consists of 6-16 amino acid residues folded into a rigid, tightly packed loop in which the N- and C-terminal ends are ...

Half-life

Biology; Biochemistry

When a property (e.g. radioactivity, enzyme activity, etc.) decreases at a rate proportional to its concentration, the time, t ½ , taken for the property to decrease to one-half its initial value; ...

Polymorphism

Biology; Biochemistry

Appearance in several forms, e.g. of a protein that is subject to tissue-specific post-translational modification, or of mRNA that is processed through alternative splice sites; also the appearance ...
