1. the manufacture method of dipeptides, it is characterized in that thering is by having to produce the ability that is generated the protein of dipeptides activity by a kind of above amino acid, and the microorganism with the ability of producing this kind at least 1 seed amino acid in above amino acid is cultivated in substratum, make dipeptides in this substratum, generate, accumulate, from this substratum, reclaim dipeptidesWherein, when microorganism can only produce 1 seed amino acid, described substratum is the substratum that adds other 1 seed amino acid,Wherein microorganism is the microorganism that belongs to Escherichia (Escherichia), andThe protein that wherein has the active protein that generates dipeptides by a kind of above amino acid and be the DNA encoding that the base sequence of any expression in sequence number 9~
