Changes in pCa₅₀

ΔpCa₅₀	WT	L29Q
Before/after cTnC-exchange	+0.06 ± 0.044	+0.06 ± 0.030
Before/after cTnC-exchange + PPlc	−0.04 ± 0.030	−0.08 ± 0.030
PPlc, before/after PKA	+0.18 ± 0.004	+0.20 ± 0.022

Table 4 summarizes the changes in pCa₅₀ induced in skinned fibers (1.) by exchange with the recombinant hcTnCs (WT/L29Q), (2.) by exchange with the recombinant cTnCs and additional treatment with phosphatase, and (3.) the ΔpCa₅₀ induced by incubation of the phosphatase-treated, exchanged fibers with PKA
