A systematic study of labelling an α-helix in a protein with a lanthanide using IDA-SH or NTA-SH tags
{{output}}
The previously published IDA-SH and NTA-SH tags are small synthetic lanthanide-binding tags derived from cysteine, which afford site-specific lanthanide labelling by disulfide-bond formation with a cysteine residue of the target protein. Following attachment t... ...
