Substrate translocation via Mep2^H194E induces a pH decrease.

<p>Haploid triple-<i>mepΔ</i> cells (31019b) were transformed with pMep2-pHluorin (A), pMep2^D186N-pHluorin (B) and pMep2^H194E-pHluorin (C) and grown in a buffered minimal medium (pH = 6.1) containing 0.1% proline. Evolution of pH, corrected for negative control variations (delt... View More
