Nucleotide sequences and genomic constitution of five tryptophan genes of Lactobacillus casei.

Journal of biochemistry - 1 Feb 1990

Natori Y, Kano Y, Imamoto F

Abstract excerpt

Five trp genes, trpD, trpC, trpF, trpB, and trpA, of Lactobacillus casei were cloned by transformation of tryptophan auxotrophic mutants of the respective trp genes in Escherichia coli. These trp genes appear to constitute an operon and are located in the above order in a segment of DNA of 6,468 base pairs. The entire nucleotide sequence of this DNA segment was determined. Five contiguous open reading frames in...
