Abstract
The present invention relates to a DNA fragment of 3,563 base pairs containing a gene coding for tannase and derived from a microorganism belonging to the genus Aspergillus, with the following restriction enzyme map: ##STR1## B: Bam HI, H: Hind III, K: Kpn I, S: Sal I, X: Xba I; a DNA fragment containing a tannase gene coding for the amino acid sequence of (SEQ ID NO:4); a recombinant plasmid comprising the DNA fragment containing the tannase gene inserted into a plasmid vector; a process for producing tannase, comprising culturing a microorganism belonging to the genus Aspergillus capable of producing tannase in medium with the recombinant plasmid, and recovering tannase from the culture; and a promoter represented by the nucleotide sequence of (SEQ ID NO:1). Tannase can be efficiently produced according to the present invention.
