Sterigmatocystin Sterigmatocystin is a xanthone isolated by a number of groups in the 1950s as a mycotoxin produced by several species of Aspergillus associated with food and grain contamination. Sterigmatocystin is structurally related to the aflatoxins and while it is considered to be mutagenic, teratogenic and carcinogenic, it is less widespread and potent than the aflatoxins. Sterigmatocystin in the presence of microsomes covalently binds to DNA. It uncouples oxidative phosphorylation but, unlike the aflatoxins, does not induce mitochondrial swelling or hinder Ca2+-induced swelling of mitochondria. More recently, sterigmatocystin has been shown to. Group: Biochemicals. Grades: Highly Purified. CAS No. 10048-13-2. Pack Sizes: 1mg. US Biological Life Sciences. USBiological 13

sterol 22-desaturase A heme-thiolate protein (P450). The enzyme, found in yeast and plants, catalyses the introduction of a double bond between the C-22 and C-23 carbons of certain sterols. In yeast the enzyme acts on ergosta-5,7,24(28)-trien-3β-ol, a step in the biosynthesis of ergosterol. The enzyme from the plant Arabidopsis thaliana acts on sitosterol and 24-epi-campesterol, producing stigmasterol and brassicasterol, respectively. Group: Enzymes. Synonyms: ERG5 (gene name); CYP710A (gene name). Enzyme Commission Number: EC 1.14.19.41. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-1006; sterol 22-desaturase; EC 1.14.19.41; ERG5 (gene name); CYP710A (gene name). Cat No: EXWM-1006. Creative Enzymes
sterol 24-C-methyltransferase Requires glutathione. Acts on a range of sterols with a 24(25)-double bond in the sidechain.
