Metabolite Identification

Common Name

De-O-methylsterigmatocystin

Description

De-O-methylsterigmatocystin belongs to the class of organic compounds known as sterigmatocystins. These are a group of closely related fungal metabolites chemically characterized by a xanthone moiety fused to a dihydrodifurano or a tetrahydrodifurano moiety. The chemical difference among the various sterigmagocystins are the presence or absence of unsaturation at positions 2 and 3 of the difurano ring system, the substitution pattern on positions 6, 7, and 10 of the xanthone system and/or the substituent on position 3 of the difurano system. They are produced by Aspergilus spp. and Bipolaris spp. De-O-methylsterigmatocystin is a mycotoxin of Aspergillus versicolor. De-O-methylsterigmatocystin is an extremely weak basic (essentially neutral) compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as sterigmatocystins. These are a group of closely related fungal metabolites chemically characterized by a xanthone moiety fused to a dihydrodifurano or a tetrahydrodifurano moiety. The chemical difference among the various sterigmagocystins are the presence or absence of unsaturation at positions 2 and 3 of the difurano ring system, the substitution pattern on positions 6, 7, and 10 of the xanthone system and/or the substituent on position 3 of the difurano system. They are produced by Aspergilus spp. And Bipolaris spp.

Enzyme Details

1. UDP-glucuronosyltransferase 1-1

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
Gene Name:: UGT1A1
