Cloning, sequencing, and expression of the araE gene of Klebsiella oxytoca 8017, which encodes arabinose-H+ symport activity.

ABSTRACT

Southern analysis of the genomic DNA from species of the family Enterobacteriaceae, using a probe derived from the Escherichia coli araE gene, which encodes an arabinose-H+ symporter, detected araE in Salmonella, Citrobacter, Klebsiella, and Enterobacter spp. The Klebsiella oxytoca araE gene was cloned, sequenced, and expressed to compare its properties with those of araE from E. coli.
