Two-dimensional homochromatography

Biology; Biochemistry

A form of displacement chromatography in which, after an initial separation in the first dimension of a labelled oligomer (e.g. an oligoribonucleotide), separation in the second dimension proceeds in ...

Cluster of orthologous groups (COG)

Biology; Biochemistry

A collection of homologous genes that are useful for study of evolutionary relationships. A COG consists of orthologues (homologous genes that have diverged in different species from a common ...

Difference Fourier method

Biology; Biochemistry

A technique of X-ray crystallography for solving the structure of a protein-ligand complex once the structure of the original protein has been deduced, by determination of the difference in ...

Isoform

Biology; Biochemistry

A variant form of a protein. Isoforms may be encoded by different genes, e.g. the isoenzymes of lactate dehydrogenase, or by a single gene, the transcript of which is alternatively spliced and upon ...

Replicon

Biology; Biochemistry

A segment of the eukaryotic genome that contains several genes and is replicated as a unit from a single origin. Replication is bi-directional; its boundaries are the points where replication from ...

Propeptide

Biology; Biochemistry

The part of a protein that is proteolytically cleaved during the protein's maturation, e.g. the internal residues of proinsulin, the N-terminal residues of pepsinogen. The term is usually not used ...

Cascade

Biology; Biochemistry

A series of enzymic reactions that at each step convert an inactive enzyme into an active enzyme, which in turn activates another inactive enzyme, and thus greatly amplifies the initial signal. In a ...
