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.

Use of anti-Grp78 blocking antibodies, Grp78 small interfering RNA, and coexpression of constitutively active Akt demonstrated an essential role for surface Grp78 in T-cad ...
WebChemical biotinylation often generates heterogeneous products, which may have impaired function. Enzymatic biotinylation with E. coli biotin ligase (BirA) is highly specific in … WebThe biotinylation of proteins is the covalent coupling of biotin to an amino acid or carbohydrate moiety of the protein. Biotinylation occurs in a specific group of proteins known as carboxylases. These are enzymes that are important in several metabolic pathways, including amino acid metabolism, fatty acid biosynthesis, and gluconeogenesis.
