51V-n.m.r. analysis of the binding of vanadium(V) oligoanions to sarcoplasmic reticulum.
The binding of mono- and oligo-vanadates to sarcoplasmic reticulum was analysed by 51V-n.m.r. spectroscopy. The observations indicate that, in addition to monovanadate, the di-, tetra- and deca-vanadates are also bound to sarcoplasmic-reticulum membranes with high affinity. The binding of the vanadate oligoanions may explain some of the effects of vanadates on the conformation and crystallization of Ca2+-transport ATPase.
