Comparative roles of the cell wall and cell membrane in limiting uptake of xenobiotic molecules by Saccharomyces cerevisiae

Antimicrob Agents Chemother. 2003 Jun;47(6):2012-4. doi: 10.1128/AAC.47.6.2012-2014.2003.

Abstract

Using reversible electropermeabilization of cells and spheroplasts, we show that the cell wall and plasma membrane partly account for bleomycin resistance by acting as two independent barriers. We also report on the presence of a membrane protein that may be responsible for bleomycin internalization and toxicity in Saccharomyces cerevisiae.
