The invention provides compositions and methods for producing androstenedione (4-androstenedione), of improved purity and for modulating its production, for example by deletion or inactivation of ksdA, cxgA, cxgB, cxgC, or cxgD. The invention also provides methods and compositions, including nucleic acids that encode enzymes, for producing 1,4-androstadiene-3,17-dione (ADD) and related pathway compounds, including 20-(hydroxymethyl)pregna-4-en-3-one and 20-(hydroxymethyl)pregna-1,4-dien-3-one. The compositions of the invention include nucleic acids, probes, vectors, cells, transgenic plants and seeds, transgenic animals, kits and arrays.
本发明提供了制备雄烯二酮(4-雄烯二酮)的组合物和方法,其纯度得到改善,并可通过删除或失活 ksdA、cxgA、cxgB、cxgC 或 cxgD 等来调节其生产。本发明还提供了用于制备1,4-雄烯二烯-3,17-二酮(ADD)及其相关代谢物的方法和组合物,包括编码酶的核酸,包括20-(羟甲基)孕-4-烯-3-酮和20-(羟甲基)孕-1,4-二烯-3-酮。本发明的组合物包括核酸、探针、载体、细胞、转基因植物和种子、转基因动物、试剂盒和阵列。
