Provided is a method for efficiently producing from a ketone compound an optically active amino compound useful as an intermediate of a drug, an agricultural chemical, or the like. Provided are: a polypeptide having aminotransferase activity that is increased in stereoselectivity, heat resistance, and resistance to amine compounds compared to the wild type enzyme by means of modifying an aminotransferase derived from
Pseudomonas fluorescens
; a gene encoding the polypeptide; and a transformant that expresses the gene at a high level.
