An objective of the present invention is to provide a method for producing substance PF1022 derivatives, in particular PF1022-220 and PF1022-260, by a direct fermentation method, and a transformant to be used for this method. According to the present invention, there is provided a transformant producing substance PF1022 derivatives, which can be obtained by introducing a gene involved in a biosynthetic pathway from chorismic acid to p-aminophenylpyruvic acid into a phenylalanine auxotrophic host induced from an organism that produces a substance PF1022. According to the present invention, there is also provided a process of producing substance PF1022 derivatives, comprising steps of culturing the abovementioned transformant and collecting the substance PF1022 derivatives.
