Abstract:
An improved method for protein labeling comprising the steps of providing a synthetic small molecule tag, providing a target protein to be tagged, providing at least two enzymes for catalyzing a conjugation reaction between the tag and the target protein, incubating the tag, the protein and the enzyme, and allowing the tag to conjugate to the target protein. The tag may embody at least one structural feature of an ubiquitin C-terminus, and the structural feature may comprise a recognition sequence that is recognizable by an ubiquitin activating enzyme.
