A Feasibility Study to Evaluate Bacillus subtilis as a Host for Producing Recombinant Human Parathyroid Hormone

摘要

Background:Biosynthetic teriparatide (1–34) (TPD) is a N-terminally truncated version of human parathyroid hormone (hPTH). The recombinant form of this polypeptide has been expressed in Escherichia coli (E. coli) and approved as the first anabolic treatment of osteoporosis in the EU and the USA. Feasibility of expression and secretion of a tag- fused form of TPD into Bacillus subtilis (B. subtilis) was examined due to several advantages of B. subtilis over E. coli in production of recombinant proteins with pharmacological activities.
