ATPase assays

Sample MgATPase Vmax MgATPase pKCa K/EDTA-ATPase Ca/K-ATPase
Control 0.322 ± 0.021 5.87 ± 0.01 0.459 ± 0.021 0.066 ± 0.013
RLC exchanged 0.321 ± 0.024 5.83 ± 0.09 — —
pPDM cross-linked — — 0.0508 ± 0.013 0.038 ± 0.024

All values are reported as mean ± SE (n = 4–6). Vmax, K/EDTA-ATPase, and Ca/K-ATPase values have units of μmol/mg protein/min. Control fibers underwent a mock RLC exchange or mock pPDM treatment.
