ABSTRACT:
A mutant AOX2 promoter obtained by mutating a sequence of natural AOX2 promoter in a manner comprising at least one of the three mutation modes of (1) a region extending upstream from nucleotide 1187 inclusive and comprising at least nucleotides 845-960 is deleted, (2) nucleotide(s) is(are) replaced in region(s) in nucleotides 1274-1314, and (3) new oligonucleotide(s) is (are) inserted in region(s) in nucleotides 1274-1314, a vector carrying said mutant AOX2 promoter, a transformant into which said vector has been introduced, and a method for producing a heterologous protein, which comprises cultivating said transformant. The promoter of the present invention has remarkably enhanced activity as compared with natural AOX2 promoter, and is highly useful as a promoter to be carried in an expression vector allowing heterologous protein expression. In addition, the vector and the transformant of the invention can efficiently express and produce various useful heterologous proteins.
