Molecular biology

One of two or more structural variants of an enzyme that can occur in the same individual, often relatively specific for a particular tissue, each with unique kinetic characteristics; e.g. the heart ...

Restriction fragment length polymorphism (RFLP)

Biology; Biochemistry

The variation of size of polynulceotides which are generated by restriction endonucleases and visualised by electrophoresis and Southern blotting. Changes in the normal pattern are indicative of ...

Interspersed repetitive sequence-PCR (IRS-PCR)

Biology; Biochemistry

A method for amplification of human DNA sequences in hybrid somatic cells, using primers directed at species-specific repetitive sequences: a short interspersed repeat element (e.g. Alu) sequence, a ...

Catecholamine

Biology; Biochemistry

One of a family of phenolic compounds chemically related to catechol (1,2-dihydroxybenzene), which is derived metabolically from tyrosine; the family comprises hormones and neurotransmitters, ...

Teichoic acid

Biology; Biochemistry

A linear polymer present in Gram-positive bacterial capsules, cell walls and membranes, characterised by polyols (glycerol, ribitol, sugars), sometimes derivatized as D-alanine esters, and linked ...

Isoenzyme

Biology; Biochemistry

Methionine bristles

Biology; Biochemistry

The cluster of methionine side chains that are proposed to protrude from the surface of a signal recognition particle and provide a plastic hydrophobic environment that can interact with the ...
