TL;DR: Two monoclonal anti-B antibodies that interfered with ATPase-ATPase interactions, produced close to 50% inhibition of the rate of ATP-dependent Ca2+ transport, with significant inhibition of ATPase; this may suggest a role for ATPase oligomers in the regulation of Ca 2+ transport.

TL;DR: There is no evidence for specific interaction of the Ca2+‐ATPase with phospholipids and the temperature dependence of FET between fluorophores attached to different regions of the ATPase indicates the existence of ‘rigid’ and ‘flexible’ regions within the molecule characterized, by different degrees of thermally induced structural fluctuations.

TL;DR: Vanadate (5 mM), and to a lesser extent Ca2+ (2–20 mM), protected the Ca2-ATPase against pressure-induced changes both in the Amide I and Amide II regions of the spectrum, together with the protection of ATPase activity.

TL;DR: A combination of the energy transfer data with the structural information derived from analysis of Ca2(+)-ATPase crystals yields a structural model, in which the location of the AEDANS-, FITC- and Ca2+ sites are tentatively identified.
