Biochemistry

homomeric

Biology; Biochemistry

Descriptive of a complex of a single kind of subunit, e.g. bacterial glutamine synthetase; contrasted with heteromeric, which is descriptive of a complex of two or more kinds of subunit, e.g. ...

base flipping

Biology; Biochemistry

The distortion of a double-stranded DNA structure that disrupts a base pair and redirects one nucleoside of the pair outwards, where it can interact with a DNA-modifying enzyme such as a ...

An empirical finding that in DNA the frequency of A equals the frequency of T, and the frequency of G equals the frequency of C; later given a theoretical basis by the Watson-Crick double-helix model ...

ectoenzyme

Biology; Biochemistry

An enzyme located on the outer surface of the plasma membrane with its active site directed to the extracellular space so as to be able to catalyze reactions in the extracellular space; e.g. ...

chemotaxis

Biology; Biochemistry

The movement of a cell along the concentration gradient of a chemical, the chemotactic agent, toward its source, in the case of the chemical being a chemoattractant, or away, in the case of a ...

tight junction

Biology; Biochemistry

The seal that closes the gap between adjacent epithelial cells to ensure closure of a vascular space. Transport through a tight junction is paracellular, in contrast to transcellular transport ...

biomimicry

Biology; Biochemistry

The design of structural materials according to examples from biology, e.g. a polymer strengthened by carbon fibres, inspired by the insect exoskeleton, which is a protein matrix reinforced by chitin ...
