  • Title: [Dependence of inhibition by levorin of amino acid incorporation into protoplasts and subcellular proteins of Candida albicans on the change of endocellular potassium concentration].
    Author: Obukhovskaia AS, Lishnevskaia EB, Tereshin IM.
    Journal: Biokhimiia; 1978 Jan; 43(1):127-31. PubMed ID: 341994.
    Abstract:
    Levorin is found to decrease more efficiently potassium concentration in C. albicans protoplasts under their incubation in the presence of sodium than in the medium containing the equivalent amount of potassium. Minimal inhibitory concentration of levorin for resistant C. albicans cells incubated on potassium-depeleted medium was in 4 times lower than for cells incubated in potassium-enriched medium. The decrease of membrane permeability for 14C-amino acids and their incorporation into membrane, ribosomal and soluble proteins under the effect of levorin was more pronounced when protoplasts were cultivated in sodium-containing medium than in potassium-containing one. In both media the inhibition of 14C-amino acid incorporation by levorin into ribosomal and cytosol proteins was more efficient than into membrane proteins, but these differences were less pronounced in case of potassium-containing medium.
