Biotinylation of proteins

WebMay 11, 2024 · A technique called proximity biotinylation helps scientists to pinpoint the identity of the proteins that partner together. It relies on attaching an enzyme (either BioID or TurboID) to a protein of interest; when a partner protein comes in close contact with this construct, the enzyme can attach a chemical tag called biotin to it. WebAbstract. One of the more useful tags for a protein in biochemical experiments is biotin, because of its femtomolar dissociation constant with streptavidin or avidin. Robust …
