A cDNA coding for human seminal inhibitor II was fused to the ompA-gene leader peptide for the expression in E. coli. The secreted protein is biologically active and correctly processed. Inhibitors of human leukocyte elastase were constructed by site-directed mutagenesis.
编码人精液抑制剂II的cDNA与ompA基因前导肽融合,以便在大肠杆菌中表达。分泌的蛋白质具有生物活性且加工正确。通过定点诱变构建了人白细胞弹性蛋白酶抑制剂。
