Abstract
The present invention succeeds in isolating a gene encoding an enzyme having an FMN reducing activity and a nitroreductase activity derived from luminous bacteria Vibrio fischeri (ATCC 7744), elucidating its primary structure, and producing Escherichia coli which can express the gene in large quantities. That is, the present invention provides a gene encoding an enzyme having the flavin reducing activity and the nitro-reductase activity, an enzyme produced therefrom, a recombinant vector containing the gene, and bacteria containing the recombinant vector.
