Abstract

The nature of the Yb3+-angiotensin II complex is examined by 13C nuclear magnetic resonance. The ytterbium-induced shifts of most resonances are observed to be strongly dependent on pD, while a few are observed to be largely independent of pD. These observations are shown to be consistent with stepwise binding of the lanthanide ion to the carboxylates of aspartic acid and the C-terminus.
