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.

Sinorhizobium meliloti Ser/Thr/Tyr phosphoproteome

Project description:Sinorhizobium meliloti, a facultative microsymbiont of alfalfa, should fine-tune its cellular processes to live saprophytically in soils characterized with limited nutrients and diverse stresses. In this study, TiO2 enrichment and LC-MS/MS were used to uncover the site-specific Ser/Thr/Tyr phosphoproteome of S. meliloti in minimum medium at stationary phase. There are a total of 96 unique phosphorylated sites, with a Ser/Thr/Tyr distribution of 65:32:5, in 78 proteins. Phosphoproteins identified in S. meliloti showed a wide distribution pattern regarding to functional categories, such as replication, transcription, translation, posttranslational modification, transport and metabolism of amino acids, carbohydrate, inorganic ion, succinoglycan etc. Ser/Thr/Tyr phosphosites identified within the conserved motif in proteins of key cellular function indicate a crucial role of phosphorylation in modulating cellular physiology. Moreover, phosphorylation events potentially involved in rhizobial adaptation to diverse stresses were also discussed, such as those identified in SMa0114 and PhaP2 (polyhydroxybutyrate synthesis), ActR (pH stress and microaerobic adaption), SupA (potassium stress), chaperonin GroEL2 (viability and potentially symbiosis), and ExoP (succinoglycan synthesis and secretion). These Ser/Thr/Tyr phosphosites identified herein would be helpful for our further investigation and understanding of the role of phosphorylation in rhizobial physiology.
