Secretion of the human parathyroid hormone through a microcin type I secretion system in Escherichia coli

The successful secretion of PTH variants using MccV T1SS could be considered as a new alternative for their production, since they would be recovered directly from the extracellular space without additional sequences. Furthermore, it would be a new example revealing the potential of microcin type I secretion systems to be conceived as a novel strategy for the production of recombinant peptides in E. coli.
