Abstract

The present invention relates to methods of transferring a label from suitable substrates to O6-alkylguanine-DNA alkyltransferase (AGT) fusion proteins, to suitable fusion proteins, to suitable variants of AGT, and to novel labelled fusion proteins obtained. A protein of interest is incorporated into an AGT fusion protein, the AGT fusion protein is contacted with an AGT substrate carrying a label, and the AGT fusion protein is detected and/or manipulated using the label in a system designed for recognising and/or handling the label.

Protein–protein interaction

Protein–protein interactions (PPIs) are physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by interactions that include electrostatic forces, hydrogen bonding and the hydrophobic effect. Many are physical contacts with molecular associations between chains that occur in a cell or in a living organism in a specific biomolecular context. Proteins rarely act alone as their functions tend to be regulated.

Protein

Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity.

Fusion protein

Fusion proteins or chimeric (kī-ˈmir-ik) proteins (literally, made of parts from different sources) are proteins created through the joining of two or more genes that originally coded for separate proteins. Translation of this fusion gene results in a single or multiple polypeptides with functional properties derived from each of the original proteins. Recombinant fusion proteins are created artificially by recombinant DNA technology for use in biological research or therapeutics.
