Detection of an initial burst of Ca^2^+ translocation in sarcoplasmic reticulum - Kurzmack, M.; Verjovski-Almeida, S.; Inesi, G. (Elsevier)
Rapid quench methods were used to determine Ca^2^+ uptake, ATPase phosphorylation and Pi production in the transient state of Sarcoplasmic Reticulum. It was found that within 20 milliseconds of the addition of ATP maximal levels of phosphorylated enzyme intermediate are reached and an initial burst of Ca^2^+ uptake is completed. This burst, kinetically distinct from the following transport activity, is related to the phosphorylated intermediate with a molar ratio of two.
