Description:

Mutations in the Eburicol gene impact on the activity of the Eburicol protein. Eburicol inhibit the large accumulation of C-14 methyl sterols and cell lysis when the content of ergosterol becomes too low in the actively growing cells.

Targets:

P450 (e.g. CYP17)

In vitro:

FEMS Microbiol Lett. 2009 Jun;296(2):266-73.

Sterol content analysis suggests altered eburicol 14alpha-demethylase (CYP51) activity in isolates of Mycosphaerella graminicola adapted to azole fungicides.[Pubmed: 19459949]

The recent decline in the effectiveness of some azole fungicides in controlling the wheat pathogen Mycosphaerella graminicola has been associated with mutations in the CYP51 gene encoding the azole target, the Eburicol 14alpha-demethylase (CYP51), an essential enzyme of the ergosterol biosynthesis pathway.
METHODS AND RESULTS:
In this study, analysis of the sterol content of M. graminicola isolates carrying different variants of the CYP51 gene has revealed quantitative differences in sterol intermediates, particularly the CYP51 substrate Eburicol.
CONCLUSIONS:
Together with CYP51 gene expression studies, these data suggest that mutations in the CYP51 gene impact on the activity of the CYP51 protein.

Eburicol Description

Source:	The roots of Wolfiporia cocos (Schw.) Ryv.
Solvent:	Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage:	Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C). Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
After receiving:	The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Cloning and sequence analysis of the eburicol 14alpha-demethylase gene of the obligate biotrophic grape powdery mildew fungus.[Pubmed: 9300816]

METHODS AND RESULTS:
In order to obtain molecular data concerning field resistance of Uncinula necator, the causal agent of grape powdery mildew, to sterol demethylation inhibitors, a major group of fungicides, the gene encoding the target of these compounds (Eburicol 14alpha-demethylase) was cloned and sequenced from this obligately biotrophic phytopathogenic fungus. This single-copy gene encodes a 524 amino acid protein which displays high similarity to other known sterol 14alpha-demethylases (CYP51s).
CONCLUSIONS:
The coding sequence is interrupted by two short introns at positions identical to introns in Penicillium italicum CYP51, which is the only other known CYP51 gene in which introns have been identified. Intron excision was verified by cDNA sequencing.

Eburicol, lichesterol, ergosterol, and obtusifoliol from polyene antibiotic-resistant mutants of Candida albicans.[Pubmed: 326362]

METHODS AND RESULTS:
Two classes of polyene-resistant mutants were isolated from survivors of N-methyl-N'-nitro-N-nitrosoguanidine treatment of a wild-type Candida albicans. An analysis of the major sterols of one class revealed an accumulation of lichesterol and fecosterol while the other class accumulated Eburicol, obtusifoliol, and lanosterol with minor quantities of C28 sterols.
