Hummel CS, Lu C, Loo DD, Hirayama BA, Voss AA, Wright EM. Glucose transport by human renal Na⁺/d-glucose cotransporters SGLT1 and SGLT2. Am J Physiol Cell Physiol 300: C14–C21, 2011. First published October 27, 2010; doi:10.1152/ajpcell.00388.2010 (http://ajpcell.physiology.org/content/300/1/C14.full)—In materials and methods, the relationship of K_d and K_i to On- and Off- rate constants (k_On and k_Off) is incorrect in the text. In the paragraph following Eq. 7, the second sentence should be corrected to read as follows: “The K_i and k_On were used, given that the ratio k_Off/k_On is the dissociation constant K_d and the K_d is the zero substrate limit of the K_i for phlorizin:

$$k_{\text{Off}}/k_{\text{On}}=K_{\mathrm{d}}\approx K_{\mathrm{i}}$$

and thus:

$$k_{\text{On}}=k_{\text{Off}}/K_{\mathrm{i}}$$ (8)
