Molecular biology

The RNA that serves in protein synthesis as an interface between mRNA and amino acids. It carries an anticodon sequence that pairs bases with a codon of mRNA, and it binds an amino acid at its 3'-end ...

Electron sink

Biology; Biochemistry

In discussions of enzyme mechanisms, a group that can pull electrons from a reactive centre and thus stabilise an electron-deficient intermediate or transition state, e.g. pyridoxal phosphate ...

Mitochondrion

Biology; Biochemistry

An organelle of eukaryotic cells that is the site of oxidative phosphorylation, the tricarboxylic acid cycle, β-oxidation, etc., and is composed of a relatively permeable outer membrane and a deeply ...

Bohr effect

Biology; Biochemistry

The decrease in the affinity of haemoglobin for oxygen that occurs when the haemoglobin solution is made more acid above pH 6. The opposite occurs below pH 6; hence the physiological phenomenon is ...

Pyrophosphorylation

Biology; Biochemistry

A post-transcriptional modification of a protein, e.g. the transfer of a phosphate group from pentaphosphatyl-inositol-pyrophosphate to a phopsphoprotein, resulting in a pyrophosphoryl protein and a ...

Cross-link

Biology; Biochemistry

In protein chemistry, a natural or synthetic covalent bond between protein side chains; it can be directly between them or mediated by a spacer group. In carbohydrate and nucleic acid chemistry, a ...

Organ targeting

Biology; Biochemistry

The homing of cells or viruses to specific tissues or organs, which is facilitated by organ-selective address molecules on the target tissue surface that tightly bind to cell-specific markers on the ...
