  • The Arabidopsis <i>dwarf1</i> Mutant Is Defective in the Conversion of 24-Methylenecholesterol to Campesterol in Brassinosteroid Biosynthesis1

    Abstract

    Since the isolation and characterization of dwarf1-1 (dwf1-1) from a T-DNA insertion mutant population, phenotypically similar mutants, including deetiolated2 (det2),constitutive photomorphogenesis and dwarfism(cpd), brassinosteroid insensitive1 (bri1), and dwf4, have been reported to be defective in either the biosynthesis or the perception of brassinosteroids. We present further characterization ofdwf1-1 and additional dwf1 alleles. Feeding tests with brassinosteroid-biosynthetic intermediates revealed that dwf1 can be rescued by 22α-hydroxycampesterol and downstream intermediates in the brassinosteroid pathway. Analysis of the endogenous levels of brassinosteroid intermediates showed that 24-methylenecholesterol in dwf1 accumulates to 12 times the level of the wild type, whereas the level of campesterol is greatly diminished, indicating that the defective step is in C-24 reduction. Furthermore, the deduced amino acid sequence of DWF1 shows significant similarity to a flavin adenine dinucleotide-binding domain conserved in various oxidoreductases, suggesting an enzymatic role for DWF1. In support of this, 7 of 10 dwf1 mutations directly affected the flavin adenine dinucleotide-binding domain. Our molecular characterization of dwf1 alleles, together with our biochemical data, suggest that the biosynthetic defect indwf1 results in reduced synthesis of bioactive brassinosteroids, causing dwarfism.

    摘要

    自从从T-DNA插入突变体群体中分离和表征了矮生1-1(dwf1-1)以来,类似表型的突变体,包括去叶绿醇2(det2),成熟光形态和侏儒(cpd),油菜素内酯不敏感1(bri1)和dwf4,已被报道存在生物合成或油菜素内酯感受的缺陷。我们进一步表征了dwf1-1和其他dwf1等位基因。用油菜素内酯生物合成中间体进行喂食实验表明,dwf1可以通过22α-羟基茎草甾醇和油菜素内酯途径下的中间体来拯救。对内源性油菜素内酯中间体水平的分析表明,dwf1中的24-亚甲基胆固醇累积到野生型水平的12倍,而茎草甾醇的水平大大降低,表明缺陷步骤在C-24还原中。此外,DWF1的推导氨基酸序列显示与各种氧化还原酶中保守的黄素腺嘌呤二核苷酸结合域具有显著的相似性,表明DWF1具有酶促作用。支持这一点的是,10个dwf1突变中的7个直接影响黄素腺嘌呤二核苷酸结合域。我们对dwf1等位基因的分子特征化,以及我们的生化数据,表明dwf1中的生物合成缺陷导致生物活性油菜素内酯的合成减少,从而引起侏儒症。

  • The Arabidopsis <i>DIMINUTO</i>/<i>DWARF1</i> Gene Encodes a Protein Involved in Steroid Synthesis

    We have identified the function of the Arabidopsis DIMINUTO/DWARF1 (DIM/DWF1) gene by analyzing the dim mutant, a severe dwarf with greatly reduced fertility. Both the mutant phenotype and gene expression could be rescued by the addition of exogenous brassinolide. Analysis of endogenous sterols demonstrated that dim accumulates 24-methylenecholesterol but is deficient in campesterol, an early precursor of brassinolide. In addition, we show that dim is deficient in brassinosteroids as well. Feeding experiments using deuterium-labeled 24-methylenecholesterol and 24-methyldesmosterol confirmed that DIM/DWF1 is involved in both the isomerization and reduction of the Δ24(28) bond. This conversion is not required in cholesterol biosynthesis in animals but is a key step in the biosynthesis of plant sterols. Transient expression of a green fluorescent protein–DIM/DWF1 fusion protein and biochemical experiments showed that DIM/DWF1 is an integral membrane protein that most probably is associated with the endoplasmic reticulum.
    通过分析dim突变体,我们确定了拟南芥DIMINUTO/DWARF1(DIM/DWF1)基因的功能。突变体的表型和基因表达都可以通过添加外源黄铜内酯来挽救。对内源性固醇的分析表明,dim 能积累 24-亚甲基胆固醇,但缺乏铜绿酸内酯的早期前体--坎贝特醇。此外,我们还发现 dim 也缺乏铜绿素类固醇。使用氘标记的 24-亚甲基胆固醇和 24-亚甲基去甲胆固醇进行的喂养实验证实,DIM/DWF1 参与了 Δ24(28) 键的异构化和还原。这种转化在动物体内的胆固醇生物合成中不是必需的,但却是植物甾醇生物合成的关键步骤。绿色荧光蛋白-DIM/DWF1 融合蛋白的瞬时表达和生化实验表明,DIM/DWF1 是一种整体膜蛋白,很可能与内质网有关。

    The membrane-bound sterol delta 24-reductase (24-reductase) catalyses anaerobic reduction of the 24(25)-enes of lanosterol and other obligatory intermediates of cholesterol biosynthesis from lanosterol. A novel assay method and properties of the 24-reductase are described. More than a 120-fold induction of the 24-reductase activity was achieved by feeding rats a diet containing 5% cholestyramine plus

    the sterol isomerization reaction are inhibited by the high affinity EBP ligand trifluoperazine, as is the case in mammalian cells but not in wild type yeast cell. In contrast, the recombinant strains are much less susceptible to the sterol inhibition effect of haloperidol and fenpropimorph, as compared with wild type yeast strains. Our results strongly suggest that EBP and delta8-delta7 sterol isomerase
    Delta8-delta7固醇异构酶是真核生物中固醇生物合成途径中的必需酶。该内质网驻留膜蛋白催化δ8-固醇向其相应的δ7-异构体的转化。到目前为止,尚无用于高真核生物固醇异构酶的序列数据,我们已经通过对酿酒酵母中相应缺陷的功能性互补,克隆了鼠固醇异构酶编码的cDNA。从cDNA开放阅读框推导出的氨基酸序列与人emopamil结合蛋白(EBP)高度相似,EBP是一种功能未知的蛋白质,构成神经保护药物的分子靶标。酵母固醇异构酶编码序列已被人EBP或其鼠类同系物取代的酵母菌株,在体内和体外均可恢复将delta8-甾醇转化为delta7-固醇的能力。在这些重组菌株中,细胞增殖和固醇异构化反应都被高亲和力的EBP配体三氟哌嗪抑制,就像在哺乳动物细胞中而不是在野生型酵母细胞中一样。相比之下,与野生型酵母菌株相比,重组菌株对氟哌啶醇和苯丙酸吗啡的甾醇抑制作用的敏感性要低得多。我们的结果强烈表明,EBP
