A DNA sequence coding for mature human leukocyte interferon D (LeIF-D) was linked with DNA fragments of the 5'-flanking sequences of the Saccharomyces cerevisiae (yeast) alcohol dehydrogenase I gene in a plasmid capable of autonomous replication and selection in both yeast and Escherichia coli. Yeast cells transformed by these plasmids synthesize up to 1 x 10(6) molecules of biologically active LeIF-D per cell.
编码成熟人白细胞干扰素D(LeIF-D)的DNA序列与酿酒酵母(酵母)乙醇脱氢酶I基因5'侧翼序列的DNA片段连接在一个能够在酵母和大肠杆菌中自主复制和筛选的质粒中。用这些质粒转化的酵母细胞每个细胞可合成多达1×10⁶个生物活性LeIF-D分子。
