title: Synthesis, cloning and expression in Escherichia coli of the gene coding for the trypsin inhibitor from Cucurbita pepo.
abstract: A chemically synthesized gene coding for the serine proteinase inhibitor CPTI II was cloned in E. coli and its expression was investigated in cytoplasmic and secretion systems. Under all conditions investigated the biologically active form of the inhibitor was found only in the latter system, although the yield was rather low.
