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 ...

Homology

Biology; Biochemistry

The similarity in base sequences of genes or amino acid sequences of proteins that denotes a common evolutionary origin; also the similarity of structure or function of proteins that is due to a ...

Picket fence porphyrin compound

Biology; Biochemistry

A model oxygen-binding porphyrin in which bulky side chains on one face of the ring permit binding of molecular oxygen while preventing oxidation of Fe 2+ , which is co-ordinated on the other face of ...

Peptide Velcro

Biology; Biochemistry

A description of helix-helix interactions in which side chains of two parallel, adjacent helices closely interact due to complementary shapes and electrostatic interactions, e.g. the leucine zipper ...

Beta (β)-oxidation

Biology; Biochemistry

The series of enzymic reactions that oxidises fatty acyl-CoA esters and shortens them by removal of the C-terminal two carbon atoms as acetyl-CoA. More narrowly, it is the oxidation of a compound, ...
