K m and V max kinetic parameters for transporter‐mediated uptake of metformin

Transporter Kinetic parameters (±SE)
K m (μmol/L) V max (pmol/min/mg protein)
OCT1 5422 ± 369 9370 ± 297
OCT2 1608 ± 175 32918 ± 1165
MATE1 4565 ± 903 141000 ± 12283
MATE2‐K 2986 ± 817 32147 ± 3401

K m, Michaelis–Menten constant; SE, standard error from fitting; V max maximal velocity of uptake.
