    • Essentially pure curculin B is disclosed. A process for producing curculin B, includes the steps of: culturing a transformed cell or microorganism containing a recombinant DNA containing a base sequence encoding curculin B, whereby curculin B is produced by the transformed cell or microorganism, and isolating curculin B from the transformed cell or microorganism. A DNA encoding mature or premature curculin B is also disclosed. DNA including a base sequence encoding curculin B, is produced by: separating a fraction containing a curculin B mRNA from Curculigo latifolia, preparing a single-stranded DNA from the mRNA using reverse transcriptase, preparing a double-stranded DNA from the single-stranded DNA, inserting the double-stranded DNA into a vector, transforming a host with the vector to produce a cDNA library, and isolating a cDNA encoding curculin B from the library, using one or more synthesized DNA's containing a base sequence coding for a partial amino acid sequence elucidated from curculin A purified from Curculigo latifolia, as a probe.
    • 本发明公开了纯的仙茅素B. 制备仙茅素B的方法包括以下步骤:培养含有含有编码仙人素B的碱基序列的重组DNA的转化细胞或微生物,由此由转化细胞或微生物产生仙茅素B,并从转化细胞中分离仙茅素B 或微生物。 还公开了编码成熟或过早的仙人素B的DNA。 包括编码仙人素B的碱基序列的DNA是通过以下步骤制备的:通过使用逆转录酶分离含有仙客来角质酪蛋白B mRNA的级分,使用逆转录酶从mRNA制备单链DNA,从单链DNA制备双链DNA 将双链DNA插入载体中,用载体转化宿主以产生cDNA文库,并使用一个或多个合成的DNA从文库中分离编码仙c素B的cDNA,该DNA含有编码部分氨基酸的碱基序列 作为探针,从仙客来自仙客来的仙人素A中阐明。
