| Abstract |
The gene araF, the product of which is the L-arabinose-binding protein--a component of the high-affinity L-arabinose transport system, was located on the Escherichia coli linkage map at 45 min. We established this location using bacteriophage P2 eductates and bacteriophage P1 cotransduction frequencies with the adjacent genetic loci, his (histidine biosynthesis) and mgl (methylgalactoside transport). In addition, we isolated a number of mutants that phenotypically exhibited altered high-affinity L-arabinose transport capacities. At least two of these mutations were located in the araF gene, as binding protein purified from these strains exhibited altered in vitro arabinose-binding properties. |
