A cell which is introduced with a DNA coding for a protein defined in the following (A) or (B):(A) a protein which has the amino acid sequence of SEQ ID NO: 2 shown in Sequence Listing;(B) a protein which has the amino acid sequence of SEQ ID NO: 2 shown in Sequence Listing including substitution, deletion, insertion, addition, or inversion of one or several amino acids, and has activity to promote methanol dehydrogenase activity, in such a manner that the protein encoded by the DNA can be expressed, is cultured in a medium so that the protein having an activity to promote methanol dehydrogenase activity should be produced and accumulated in the medium, and the protein is collected from the medium. The present invention provides a novel activator of methanol dehydrogenase, DNA coding for it, cell expressing the DNA, and method for producing the activator.
