Difference in the late ergosterol biosynthesis between yeast spheroplasts and intact cells.
A comparative study on post-squalene sterol synthesis in intact yeast cells and spheroplasts was carried out with strains from three genera (Saccharomyces cerevisiae, Schizosaccharomyces pombe, Pichia pastoris) as well as with engineered S. cerevisiae cells altered in regard to the late ergosterol synthesis pathway. A common outcome of incubation experiments with radioactive acetate was that in...
متن کاملFactors Determining the Ergosterol Content of Yeast
Following the discovery of ergosterol by Tanret (l), Gerard (2) observed that not only ergot, but fungi in general, contain it. Gerard was the first to recognize ergosterol in yeast, although Nageli (3) had earlier obtained a yeast “cholesterol” in crude form. In traces ergosterol is now known to be widely distributed in both plant and animal kingdoms, but the fungi, and particularly the yeasts...
متن کاملRegulation of early enzymes of ergosterol biosynthesis in Saccharomyces cerevisiae.
In order to determine the regulation mechanisms of ergosterol biosynthesis in yeast, we developed growth conditions leading to high or limiting ergosterol levels in wild type and sterol-auxotrophic mutant strains. An excess of sterol is obtained in anaerobic sterol-supplemented cultures of mutant and wild type strains. A low sterol level is obtained in aerobic growth conditions in mutant strain...
متن کاملThe functional importance of structural features of ergosterol in yeast.
As an approach to the study of the relationship between the structure of sterols and their capacity to function in the lipid leaflet of membranes, various sterols were examined for their ability to support the growth of anaerobic Saccharomyces cerevisiae. A marked dependence on precise structural features was observed in growth-response and morphology. Of the chemical groups which distinguish e...
متن کاملInhibition of Ergosterol Biosynthesis by Etaconazole in Ustilago maydis
Fungal Lipids, Ergosterol, Inhibition, Etaconazole, Fungicide The triazole fungicide etaconazole (C G A 64 251) interferes with the ergosterol biosynthesis in Ustilago maydis by inhibiting the C-14 demethylation o f the sterol nucleus. During the late log growth phase o f U. maydis a novel endogenous sterol metabolite (14x-methyl-ergosta-8,24(28)dien-3/?,6a-diol) was discovered and analyzed, wh...
