Abstract: A recombinant vector according to an embodiment of the present invention may produce fibroblast growth factor 19 (FGF19) having enhanced solubility. The synonymous codon substitution variant fibroblast growth factor 19 (scvhFGF19) and chaperone ΔssDsbC may be simultaneously and independently expressed in a host cell into which the recombinant vector is introduced, thereby it is possible to overexpress the fibroblast growth factor 19 in a soluble state, due to when not utilizing tags such as an existing fusion partner there is no change in the amino acid, which is a problem generated in the removal process.
