The efficient soluble expression of human epidermal growth factor (hEGF) was achieved by using functional fusion partners in cytoplasm and periplasm of Escherichia coli (E. coli). hEGF was over-expressed in inactive inclusion body form in cytoplasm of E. coli due to improper disulfide bond formation and hydrophobic properties, resulting in about 5.9 mg/L in flask culture. Six functional fusion partners were introduced by linking to N-terminal part of hEGF gene for the high-level expression of soluble and active hEGF in cytoplasm and periplasm region. Three fusion partners such as ATS, thioredoxin and lipase for cytoplasmic expression, and three fusion partners such as periplasmic cystein oxidoreductases (DsbA and DsbC) and maltose binding protein for periplasmic expression were investigated. hEGF fused with ATS and DsbA showed over 90% of solubility in cytoplasm and periplasm, respectively. Especially DsbA was found to be an efficient fusion partner for soluble and high-level expression of hEGF, resulting in about 18.1 mg/L, that is three-fold higher concentration compared to that of insoluble non-fusion hEGF.
