Na buffering parameters
Parameter | Value | Units* |
---|---|---|
Kon | 0.1 | mM−1s−1 |
Koff | 1 | s−1 |
Kd | 10 | mM |
Bmax junction | 3.7 | mM |
Bmax SL | 1.65 | mM |
Bmax cytosol | 0 | mM |
All units are mmol/l cytosol. Concentrations in the actual compartments can be calculated assuming 11% of membrane-bound components are in the junctional cleft and 89% are in the SL compartment.
