Abstract
Coryneform bacteria promoter DNA fragments are disclosed having greater promoter strength in Coryneform bacteria cells than the tac promoter obtained by fusing Escherichia coli trp promoter and lac promoter. The promoter function of some of the promoter DNA fragments is controllable by replacing at least one of the culture-medium ingredients with at least one other ingredient. The sizes and nucleotide sequences of such promoter DNA fragments are also disclosed.
