Control of gluconate utilization in Sinorhizobium meliloti.

ABSTRACT: The Sinorhizobium meliloti megaplasmid pSymA has previously been implicated in gluconate utilization. We report a locus on pSymA encoding a putative tripartite ATP-independent periplasmic (TRAP) transporter that is required for gluconate utilization. The expression of this locus is negatively regulated by a GntR family regulator encoded adjacent to the transporter operon.
