L-Arabinose transport and the L-arabinose binding protein of Escherichia coli.
The active accumulation of L-arabinose by arabinose induced cultures of Escherichia coli is mediated by 2 independent transport mechanisms. One, specified by the gene locus araE, is membrane bound and possesses a relatively "low affinity". The other, specified in part by the genetic locus araF, contains as a functional component the L-arabinose binding protein and functions with a "high affinity" for the substrate. The L-arabinose binding protein has been purified, partially characterized, crystallized, and sequenced.
