Metabolite Identification
Common NameEburicol
DescriptionEburicol is a sterol metabolite belonging to the chemical class of triterpenoids. It is an intermediate in the biosynthesis of ergosterol, a key component of fungal cell membranes. Eburicol is synthesized from lanosterol through the action of Erg6A, and its conversion to 14-methylergosta-8,24(28)-dien-3β,6α-diol is catalyzed by the sterol C5-desaturase (ERG3). Eburicol plays significant roles in various biochemical pathways, including the modulation of antifungal resistance mechanisms in fungi. For instance, its accumulation is linked to the antifungal activity of azoles against Aspergillus fumigatus, where it drives the synthesis of fungicidal cell wall carbohydrate patches (PMID:39060235 ). Additionally, eburicol levels are affected by the enzymatic activity of CYP51A and B, which require eburicol for their function (PMID:39728316 ). In strains deficient in ergosterol synthesis, such as Δerg6, eburicol content increases alongside zymosterol, indicating its role in sterol metabolism (PMID:39477913 ). Furthermore, the turnover of eburicol is enhanced during the upregulation of cprA or cyp51A, highlighting its dynamic involvement in fungal growth and resistance (PMID:37815358 ).
