Pivotal Enzyme in Glutamate Metabolism of Poly-g-Glutamate-Producing Microbes

Life, 2013
The extremely halophilic archaeon Natrialba aegyptiaca secretes the L-homo type of poly-g-glutamate (PGA) as an extremolyte. We examined the enzymes involved in glutamate metabolism and verified the presence of L-glutamate dehydrogenases, L-aspartate ...

Metabolic Engineering of Bacillus amyloliquefaciens to Efficiently Synthesize L-Ornithine From Inulin

Frontiers in Bioengineering and Biotechnology, 2022
Bacillus amyloliquefaciens is the dominant strain used to produce γ-polyglutamic acid from inulin, a non-grain raw material. B. amyloliquefaciens has a highly efficient tricarboxylic acid cycle metabolic flux and glutamate synthesis ability.

The dnaJ (hsp40) Locus in Rhizobium leguminosarum bv. phaseoli Is Required for the Establishment of an Effective Symbiosis with Phaseolus vulgaris

Molecular Plant-Microbe Interactions, 2000
P121R25 is a Tn5-induced mutant of the effective Rhizobium leguminosarum bv. phaseoli strain P121R that is unable to use glutamate as the sole carbon and nitrogen source and is defective in symbiotic nitrogen fixation.

The role of malate in the synthesis of glutamate in Pisum arvense roots

Acta Societatis Botanicorum Poloniae, 2014
The in vivo and in vitro activities of NADH-dependent glutamate synthase in excised Pisum arvense roots increased several-fold under the influence of malate while pyruvate oxaloacctate. citrate and succinate inhibited this entyme.
