Biochemistry

Module

Biology; Biochemistry

In protein chemistry, a building block from which larger proteins are constructed; a recurring folding pattern in proteins, examples of which may have amino acid sequences that are homologous or ...

One of a class of redox-sensitive proteins and other enzymes characterised by a prosthetic group of one to four iron atoms, depending upon the protein, which are co-ordinated with the sulphur atoms ...

Dideoxynucleotide fingerprinting (ddF)

Biology; Biochemistry

A method for the detection of mutation in a DNA fragment. The DNA serves as a template for replication using a mixture of four normal deoxynucleotides plus one dideoxyribonucleotide. Electrophoresis ...

Isotope effect

Biology; Biochemistry

The effect on kinetics of the substitution of one isotope for another in a bond that must be broken in a rate-limiting step (primary isotope effect); especially prominent in the case of cleavage of a ...

Disc-gel electrophoresis

Biology; Biochemistry

A technique for electrophoresis of single samples in an open-ended tube. The polyacrylamide stationary phase is polymerized in situ. During electrophoresis the ends of the tube are immersed in upper ...

Translocation channel

Biology; Biochemistry

A multi-protein structure through which other proteins may be exported across the plasma membrane (bacteria), or nascent proteins may pass from the cytosol into the endoplasmic reticulum or damaged ...

Combinatorial

Biology; Biochemistry

Descriptive of procedures or processes that generate a diversity of molecules (e.g. nucleic acid or protein sequences; related chemical structures) that can be screened for a desired property. The ...
