Protein SDSL strategies. Paramagnetic moieties represented by X˙: (a) Canonical AA/Cysteine labeling, (b) solid phase peptide synthesis followed by protein ligation, (c) chelation by genetically encoded peptide tags, (d) conjugation of ncAA with side chain Y with labeling molecule X˙-R, and (e) direct encoding of paramagnetic ncAA.
