摘要：

A hypothesis of the flippase nature of the glutathione S-conjugate transport is presented. Experimental premises for this hypothesis include interaction of glutathione S-conjugates with the membrane, as demonstrated by their effects on membrane fluidity, quenching of 1-(4-trimethylammoniumphenyl)-6-phenyl-1,3,5-hexatriene fluorescence and induction of echinocytosis by 2,4-dinitrophenyl-S-glutathione (DNP-SG). This hypothesis can rationalize, i. a., observations of the enhancement of DNP-SG transport by butanol and stimulation of erythrocyte membrane Mg2+-ATPase activity by albumin-coupled DNP-SG.
