27 m(-1) s(-1) in aqueous environments at room temperature, which is suitable for biological labeling applications. The VBAs are shown to be biocompatible, non-toxic, and highly stable in aqueous media and cell lysate. Furthermore, VBAs can be used orthogonally to the strain-promotedalkyne-azidecycloaddition for protein modification, making them attractive complements to the bioorthogonal molecular

The invention relates to a polypeptide comprising an amino acid having a cyclopropene group wherein said cyclopropene group is joined to the amino acid via a carbamate group. Suitably the cyclopropene group is a 1,3-disubstituted cyclopropene such as a 1,3-di methylcyclopropene. Suitably the cyclopropene group is present as a residue of a lysine amino acid. The invention also relates to methods of making the polypeptides. The invention also relates to an amino acid comprising cyclopropene wherein said cyclopropene group is joined to the amino acid moiety via a carbamate group.

Rapid, one-pot, concerted, site-specific labeling of proteins at genetically encoded unnatural amino acids with distinct small molecules at physiological pH, temperature, and pressure is an important challenge. Current approaches require sequential labeling, low pH, and typically days to reach completion, limiting their utility. We report the efficient, genetically encoded incorporation of alkyne- and cyclopropene-containing amino acids at distinct sites in a protein using an optimized orthogonal translation system in E. coli. and quantitative, site-specific, one-pot, concerted protein labeling with fluorophores bearing azide and tetrazine groups, respectively. Protein double labeling in aqueous buffer at physiological pH, temperature, and pressure is quantitative in 30 mm.
