    UGT74AN1, a Permissive Glycosyltransferase from Asclepias curassavica for the Regiospecific Steroid 3-O-Glycosylation
    摘要:
    A permissive steroid glycosyltransferase (UGT74AN1) from Asclepias curassavica exhibited robust capabilities for the regiospecific C3 glycosylation of cardiotonic steroids and C-21 steroid precursors, and unprecedented promiscuity toward 53 structurally diverse natural and unnatural compounds to form O-, N-, and S-glycosides, along with the catalytic reversibility for a one-pot transglycosylation reaction. These findings highlight UGT74AN1 as the first regiospecific catalyst for cardiotonic steroid C3 glycosylation and exhibit significant potential for glycosylation of diverse bioactive molecules in drug discovery.

    评估了糖基转移酶 OleD 变体作为四对强心类固醇 (CTS) 差向异构体糖基化的催化剂。本研究结果表明,OleD 催化的 CTS 糖基化受到 C-3 构型和 A/B 融合模式的显着影响。3β-OH 和 A/B 环顺式融合受到 OleD (ASP) 的青睐。C-14和C-15处的环氧化物进一步提高了生物转化率;而C-16处的乙酰基和C-17处的内酯环类型不影响生物转化。高转化率对应低K m值。分子对接模拟表明,疏水性口袋II的填充以及与Tyr115残基的相互作用可能在OleD糖基转移酶催化的糖基化反应中发挥重要作用。此外,糖基化产物对Na +、K + -ATP酶的抑制活性比相应的苷元更强。这项研究首次为 OleD (ASP) 催化的糖基化提供了立体选择性特性。

    3-epi-Bufadienolides with unique structures and lower toxicities have been isolated from toad bile. A short-chain dehydrogenase/reductase, HSE-1, was cloned from a toad liver cDNA library and verified to regulate the epimerization of bufadienolides.

    active bufadienolides with diverse modifications and trace content. In this work, based on the transcriptome and genome analyses, using a yeast-based screening platform, we obtained eight cytochrome P450 (CYP) enzymes from toads, which catalyze the hydroxylation of bufalin and resibufogenin at different sites. Moreover, a reported fungal CYP enzyme Sth10 was found functioning in the modification of bufalin
    蟾蜍二烯内酯是一类在 C17 处具有独特 α-吡喃酮环的类固醇,主要由蟾蜍产生,由 100 多种直系同源物组成。它们具有强效的强心和抗肿瘤活性,是中药蟾酥和华蟾素的活性成分。直接从蟾蜍中提取成本高昂,化学合成也很困难,限制了具有多种修饰和痕量含量的活性蟾蜍二烯内酯的获取。在这项工作中,基于转录组和基因组分析,使用基于酵母的筛选平台,我们从蟾蜍中获得了八种细胞色素P450(CYP)酶,它们在不同位点催化蟾蜍灵和resibufogenin的羟基化。此外,据报道,一种真菌 CYP 酶 Sth10 被发现在蟾蜍灵和resibufogenin的多个位点修饰中发挥作用。共生产并鉴定了15种蟾蜍二烯内酯,其中6种为首次发现。所有化合物均能有效抑制肿瘤细胞的增殖,特别是19-羟基-蟾毒灵( 2 )和1β-羟基-蟾毒灵( 3 ),它们是由CYP46A35催化蟾毒灵羟基化产生的。 CYP46A35的催化效率提

An epoxide ring at C-14 and C-15 further increases the bioconversion rate; while an acetyl group at C-16 and lactone ring type at C-17 did not influence the biotransformation. A high conversion rate corresponded to a low Km value. A molecular docking simulation showed that filling of hydrophobic pocket
