The order Rhizobiales contains numerous agriculturally, biotechnologically, and medically
important bacteria, including the rhizobia, and the genera Agrobacterium, Brucella, and …

The formation of phosphoenolpyruvate (PEP) is a major step in the gluconeogenic pathway
in which tricarboxylic acid (TCA) cycle intermediates are converted to hexose sugars. In …

The enzyme phosphoenolpyruvate carboxykinase (Pck) catalyzes the first step in the
gluconeogenic pathway in most organisms. We are examining the genetic regulation of the …

A large proportion of genes within a genome encode proteins that play a role in metabolism.
The Alphaproteobacteria are a ubiquitous group of bacteria that play a major role in a …

We have cloned and sequenced the pckA gene of Rhizobium sp. NGR234, a broad host-
range strain. The gene encodes phosphoenolpyruvate carboxykinase (PEPCK), a key …

The pckA gene of Rhizobium meliloti, encoding phosphoenolpyruvate carboxykinase, was
isolated from a genomic cosmid library by complementation of the succinate growth …

In most actinomycetes, GlnR governs both nitrogen and non-nitrogen metabolisms (eg,
carbon, phosphate, and secondary metabolisms). Although GlnR has been recognized as a …

Gluconeogenesis in Rhizobium leguminosarum MNF3841 takes place via the derepressible
enzymes phosphoenolpyruvate carboxykinase (PEPCK) and fructose bisphosphate …

Polyhydroxybutyrate (PHB) and glycogen polymers are produced by bacteria as carbon
storage compounds under unbalanced growth conditions. To gain insights into the …

The HPrK kinase/phosphatase is a common component of the phosphotransferase system
(PTS) of gram-positive bacteria and regulates catabolite repression through …
