Abstract:
A surface expression vector for fusion protein of Myo-2 peptide multimer and myostatin is provided to express the myostatin fusion protein on the surface of bacteria, and increase the blood antibody production, body weight and muscle amount of animals by orally administering the bacteria. A myostatin derived peptide Myo-2 has the amino acid sequence of SEQ ID NO:1. A Myo-2 peptide multimer is prepared by polymerizing 2-8 Myo-2 peptides. A fusion protein is prepared by fusing the Myo-2 peptide multimer with matured myostatin. A surface expression vector for fusion protein contains a gene encoding polygammaglutamic acid synthetase complex selected from pgsB(polygammaglutamic acid synthetase), pgsC and pgsA, the nucleotide sequence encoding the Myo-2 peptide multimer and a gene encoding the matured myostatin. A method for producing a fusion protein-surface expressed microorganism comprises the steps of: (a) expressing the fusion protein of myostatin derived peptide multimer and matured myostatin on the surface of microorganism by culturing a microorganism transformed with the surface expression vector; and (b) recovering the microorganism with surface expressed matured myostatin, wherein the microorganism is lactic acid bacterium. Further, the matured myostatin is be derived from mammal or birds.
