摘要：
Amplification of the LYP1 transport system in the plasma membrane of Saccharomyces cerevisiae did not change the substrate specificity, the affinity and the pH optimum of the transport system for lysine, but significantly increased the uptake velocity and accumulation ratio. The dependence of active lysine uptake and accumulation on pH is probably given by the properties of the permease itself rather than by the value of available protonmotive force.
