Abstract

Ergosterol, an important component of the fungal cell membrane, is not only essential for fungal growth and development but also very important for adaptation to stress in fungi. Ergosterol is also a direct precursor for steroid drugs. The biosynthesis of ergosterol can be divided into three modules: mevalonate, farnesyl pyrophosphate (farnesyl-PP) and ergosterol biosynthesis. The regulation of ergosterol content is mainly achieved by feedback regulation of ergosterol synthase activity through transcription, translation and posttranslational modification. The synthesis of HMG-CoA, catalyzed by HMGR, is a major metabolic check point in ergosterol biosynthesis. Excessive sterols can be subsequently stored in lipid droplets or secreted into the extracellular milieu by esterification or acetylation to avoid toxic effects. As sterols are insoluble, the intracellular transport of ergosterol in cells requires transporters. In recent years, great progress has been made in understanding ergosterol biosynthesis and its regulation in Saccharomyces cerevisiae. However, few reviews have focused on these studies, especially the regulation of biosynthesis and intracellular transport. Therefore, this review summarizes recent research progress on the physiological functions, biosynthesis, regulation of biosynthesis and intracellular transportation of ergosterol in S. cerevisiae.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
