Patent number: 5629171Abstract: 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, 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, 7-aminodeacetylcephalosporanic acid (7-ADAC); and3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of 7-ACA. The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase.Type: GrantFiled: May 11, 1995Date of Patent: May 13, 1997Assignee: Gist-Brocades B.V.Inventors: Michael J.
