    • 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 FF1022 derivatives, which can be obtained by introducing a genes involved in a biosynthetic pathway from chorismic acid to p-aminophenylpyruvic acid, including a papA gene encoding 4-amino-4-deoxychorismate synthase. which gene comprises the DNA sequence encoding the amino acid sequence of SEQ ID NO: 2; a papB gene encoding 4-amino-4-deoxyclaismate mutase, which gene comprises the DNA sequence encoding the amino acid sequence of SEQ ID NO: 4; and a papC gene encoding 4-amino-4-deoxyprepbenate dehydrogenase, which gene comprises the DNA sequence encoding the amino acid sequence of SEQ ID NO: 6, 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 derivative, comprising steps of culturing the above-mentioned transformant and collecting the substance PF1022 derivatives.
