摘要： A procedure for producing a modified 7.beta.-(4-carboxybutanamide) cephalosporinase enzyme which can be purified in a single chromatographic step. The procedure for production of the enzyme involves: mutagenizing the gene which codes for the enzyme from Acinetobacter sp. ATCC 53891 by inserting a nucleotide sequence coding for six histidine residues; fusing the mutant gene with high-efficiency promoter DNA sequences; transforming Escherichia coli cells with the fusion gene construct; growing the transformed Escherichia coli cells; and recovering the enzyme by the use of supports which contain metal chelates. 7-Aminocephalosporanic acid is an important intermediate for the manufacture of a wide range of antibacterial agents of the cephalosporin family.

摘要： Enzymatic process for the preparation of cephalosporanic 7&bgr;-(4-carboxybutanamide) acid by using the modified enzyme D-aminoacid oxidase of Trigonopsis variabilis produced in Escherichia coli. The process for the expression of the enzyme comprises: (I) isolating the DNA corresponding to gene which codes for the enzyme D-aminoacid oxidase; (II) removing the intron which is contained in said gene; (III) inserting the DNA fragment obtained into the plasmide which is capable of replication in Escherichia coli; (IV) fusing at the extremity 5′ of the structural region of the gene a synthetic assembler which contains a nucleotide sequence which codes for six histidines; (V) transforming a strain of Escherichia coli with the resulting recombinant plasmide; (VI) cultivating the transformed cells of Escherichia coli; and (VII) recovering the enzyme D-aminoacid oxidase of the former cultivation operation through affinity chromatography.
