The present disclosure relates to a novel promoter, a vector comprising the promoter, a microorganism comprising the vector, and a method for producing a target protein using the promoter. The promoter obtained by the present disclosure exhibits an increased gene expression rate compared to promoters used in a large-scale production of proteins from the existing recombinant microorganisms, and can thus be used advantageously in food, pharmaceutical, and agricultural industries in which high-yield production of functional materials from microorganisms is needed.
