  1. Boltzmann equation parameters were calculated at two pH conditions: 6.5 and 7.6 for zebrafish PepT1a (data from Fig. 5) and 6.5 and 7.5 for zebrafish PepT1b and rabbit PepT1 (data from [28]). Qmax, the maximal moveable charge; V0.5, the voltage at which half of the charge is moved; σ, slope factor of sigmoidal curve
