Molecular Cloning and Functional Expression in <i>Lactobacillus plantarum</i> 80 of <i>xylT</i> , Encoding the <scp>d</scp> -Xylose–H ⁺ Symporter of <i>Lactobacillus brevis</i>

Abstract excerpt

A 3-kb region, located downstream of the Lactobacillus brevis xylA gene (encoding D-xylose isomerase), was cloned in Escherichia coli TG1. The sequence revealed two open reading frames which could code for the D-xylulose kinase gene (xylB) and another gene (xylT) encoding a protein of 457 amino acids with significant similarity to the D-xylose-H+ symporters of E. coli, XylE (57%), and Bacillus megaterium, XylT...
