Identification and Characterization of Bacterial Diterpene Cyclases that Synthesize the Cembrane Skeleton
Digging up skeletons: We report the identification and the functional characterization of two terpene cyclases (DtcycA and DtcycB) that were mined from the genome of Streptomyces sp. SANK 60404. DtcycA and DtcycB are novel bacterial diterpene cyclases for the synthesis of the cembrane skeleton.
متن کاملCharacterization of deoxyribozymes that synthesize branched RNA.
We recently reported deoxyribozymes (DNA enzymes) that synthesize 2',5'-branched RNA. The in vitro-selected 9F7 and 9F21 deoxyribozymes mediate reaction of a branch-site adenosine 2'-hydroxyl on one RNA substrate with the 5'-triphosphate of another RNA substrate. Here we characterize these DNA enzymes with respect to their branch-forming activity. Both 9F7 and 9F21 are much more active with Mn(...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
cis or trans with class II diterpene cyclases.
Isoprenoid precursors readily undergo (poly)cyclization in electrophilic reaction cascades, presumably as internal addition of the carbon-carbon double-bonds from neighboring isoprenyl repeats readily forms relatively stable cyclohexyl tertiary carbocation intermediates. This hypothesis is agnostic regarding alkene configuration (i.e., Z or E). Consistent with this, here it is shown that certai...
متن کاملA new cembrane diterpene from the Bornean soft coral Nephthea sp.
A new cembrane diterpene, 6-acetoxy-7,8-epoxynephthenol acetate (1) was isolated along with a known compound, epoxynephthenol acetate (2), from the organic extract of a Bornean soft coral Nephthea sp. Their structures were elucidated on the basis of spectroscopic analyses and comparison with those previous literature data.
