| Abstract: | It was shown that suppression by levorin of the leucine transport into the cells of C. albicans was due to replacement of intracellular K+ by Na+ induced by the antibiotic. The alanine transport was suppressed by levorin irrespective of the ratio of the monovalent cations concentration in the medium and inside the cell. The levorin effect on the protone escape from the cells was negligible and probably played no significant role in the mechanism of the amino acid transport suppression by the antibiotic. |
