摘要： Important intermediates for preparing cephalosporin antibiotics, 7-amino-cephalosporanic acid (7-ACA) and 7-aminodeacetylcephalosporanic acid (7-ADAC), are prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); followed by the in situ expression of the following genes with which the P. chrysogenum has been transformed:
1) an expandase gene, e.g., from Cephalosporium acremonium , whose expression product converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA;
2) an hydroxylase gene whose expression product converts the 3-methyl side chain of adipoyl-7-ADCA to 3-hydroxymethyl, to give the first product, adipoyl-7-aminodeacetylcephalosporanic acid (7-ADAC); and
3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of adipoyl-7-ACA. The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.摘要翻译： 通过新型生物工艺制备头孢菌素抗生素，7-氨基头孢菌素（7-ACA）和7-氨基脱乙酰头孢菌酸（7-ADAC）的重要中间体，其中转化的产黄青霉菌株在己二酸存在下培养 生产己二酰-6-APA（6-氨基青霉烷酸）的原料; 其次是产生产黄青霉的以下基因的原位表达：1）扩增酶基因，例如头孢霉头孢菌，其表达产物将己二酰基-6-APA通过环扩展转化为己二酰-7- ADCA; 2）其表达产物将己二酰-7-ADCA的3-甲基侧链转化为3-羟甲基的羟化酶基因，得到第一产物，己二酰-7-氨基乙酰基头孢烷酸（7-ADAC）; 和3）其表达产物将3-羟甲基侧链转化为己二酰-7-ACA的3-乙酰氧甲基侧链的乙酰转移酶基因。 然后通过使用己二酰酰化酶裂解己二酰侧链制备最终产物7-ACA。 因此，整个合成使用生物工艺进行，并且是高效和经济的。

摘要： An important intermediate for preparing cephalopsporin antibotics, 7-aminodesacetoxy cephalosporanic acid (7-ADCA), is prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); and the in situ expression of an expandase gene, e.g., from Streptomyces clavuligerus , with which the P.chrysogenum has been transformed, converts the adipoyl-6-APA by ring expansion to the novel compound adipoyl-7-ADCA. The final product, 7-ADCA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.
