Figure 7. Replacing the front half (N-terminus, TM1–5 and loop) of NBCe1-A with the homologous parts of NBCn1-B.

Figure 7

A, chimeric transporter n1(1–821)/e1. B, (I–V) relationships obtained from oocytes expressing n1(1–821)/e1 in the absence (○) and presence (•) of HCO3−–CO2 (n = 5). C, representative recordings of pHi and Vm in an oocyte expressing n1(1–821)/e1. The number in parenthesis (1–821) represents amino acids of NBCn1-B. The pHi recovery from an acidification (arrow) without hyperpolarization (arrowhead) is shown. One of three experiments.
