    • PURPOSE: A serine palmitoyl transferase coding gene derived from Pichia ciferrii and a tetraacetyl phytosphingosine(TAPS) producing method using the same are provided, thereby tetraacetyl phytosphingosine(TAPS) can be mass produced with low costs. CONSTITUTION: The gene LCB2 encoding serine palmitoyl transferase and derived from Pichia ciferrii (ATCC 14091) is represented by sequence ID No. 1 described as in the description. The expression vector prACL2(KCTC-0468BP) having an endonuclease map of Fig. 3 contains the gene LCB2, CYHr gene being resistant to cycloheximide, and ribosome DNA derived from Pichia ciferrii, wherein the ribosome DNA comprises a 0.6kb non transcribed region which is obtained by cleavage with HindIII/EcoRV. A transformant is produced by transforming Pichia ciferrii with the expression vector prACL2(KCTC-0468BP). Tetraacetyl phytosphingosine(TAPS) which is a raw material of ceramides is produced by incubating the transformed Pichia ciferrii and extracting TAPS from the fermented culture, wherein ceramides are used in protecting the skin and maintaining the humidity of the skin.
    • 目的:提供从毕赤酵母(Pichia ciferrii)衍生的丝氨酸棕榈酰转移酶编码基因和使用其的四乙酰植物鞘氨醇(TAPS)生产方法,从而可以低成本批量生产四乙酰植物鞘氨醇(TAPS)。 构成:编码丝氨酸棕榈酰转移酶并衍生自毕赤酵母(ATCC 14091)的基因LCB2由描述中描述的序列ID 1表示。 具有图1的核酸内切酶图谱的表达载体prACL2(KCTC-0468BP) 3包含基因LCB2,对放线菌酮具有抗性的CYHr基因和衍生自毕赤酵母的核糖体DNA,其中核糖体DNA包含通过用HindIII / EcoRV切割获得的0.6kb非转录区域。 通过用表达载体prACL2(KCTC-0468BP)转化毕赤酵母来产生转化体。 作为神经酰胺原料的四乙酰植物鞘氨醇(TAPS)是通过将转化的毕赤酵母培养并从发酵培养物中提取TAPS产生的,其中使用神经酰胺来保护皮肤并保持皮肤湿度。

    • PURPOSE: Provided is an expression plasmid for Pichia ciferrii to insert targeted genes as many as possible into the strain when transformation of Pichia ciferrii is required. CONSTITUTION: The expression plasmid for Pichia ciferrii is obtained by the next steps of: i) separating the gene of ribosome protein L41 of sequence ID. No. 1 from Pichia ciferrii; ii) making the L41 gene resistant to cycloheximide and manufacturing plasmid pCYH1.9¬r to select transformants; iii) separating ribosome DNA and making plasmid prDX9.0 to insert targeted genes into chromosome more effectively; and iv) making a recombinant plasmid by treating ribosome DNA with restriction enzyme.
    • 目的:提供毕赤酵母在需要转化毕赤酵母时将目标基因尽可能多地插入菌株的表达质粒。 构成:通过以下步骤获得毕赤酵母的表达质粒:i)分离序列ID的核糖体蛋白L41的基因。 毕赤酵母1号; ii)使L41基因对放线菌酮具有抗性,并制备质粒pCYH1.9-r以选择转化体; iii)分离核糖体DNA,制作质粒prDX9.0,将靶基因更有效地插入染色体; 和iv)用限制酶处理核糖体DNA制备重组质粒。
