Abstract:
Single-armed DOTA-like phenylsulfonated pyridine derivatives are rigid and stable paramagnetic tags for site-specific labeling of proteins. Their reactions with a solvent-exposed protein thiol group generate a stable C-S bond and produce one single paramagnetic species in solution NMR. The generated large paramagnetic effects yield valuable long-range structural restraints for proteins.
