ABSTRACT:
A human growth hormone having a molecular weight of 20,000 daltons can be effectively secreted and produced in the periplasm of Escherichia coli by constructing a human growth hormone secretion plasmid comprising a vector DNA replicable in E. coli and a DNA fragment including a promoter, a ribosome binding site, a secretion signal coding region, which are all those of the neutral protease gene of B. amyloliquefaciens and a gene encoding 20 kD hGH placed just downstream from the secretion signal coding region; introducing the said plasmid into E. coli; and culturing the resultant transformed cells.
