Metabolite Identification
Common Name5,6-Dimethoxysterigmatocystin
Description5,6-Dimethoxysterigmatocystin 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. 5,6-Dimethoxysterigmatocystin is an extremely weak basic (essentially neutral) compound (based on its pKa). Mycotoxin production by Aspergillus multicolor.

Enzymes

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.
