The complete Corynebacterium glutamicum ATCC 13032 genome sequence and its impact on the production of L-aspartate-derived amino acids and vitamins.
TLDR
These analyses confirm the taxonomic position of C. glutamicum as related to Mycobacteria and show a broad metabolic diversity as expected for a bacterium living in the soil. Expand
Isoleucine synthesis in Corynebacterium glutamicum: molecular analysis of the ilvB-ilvN-ilvC operon
TLDR
The amounts of the ilvBNC and ilvNC transcripts increased in response to the addition of alpha-ketobutyrate to the growth medium, correlated to an increase in specific AHAS activity, whereas IR activity was not increased because of the relatively large amount of theIlvC transcript present under all conditions assayed. Expand
Identification of a thiamin-dependent synthase in Escherichia coli required for the formation of the 1-deoxy-D-xylulose 5-phosphate precursor to isoprenoids, thiamin, and pyridoxol.
TLDR
It is shown that an open reading frame at 9 min on the chromosomal map of E. coli encodes an enzyme (deoxyxylulose-5-phosphate synthase, DXP synthase) that catalyzes a thiamin diphosphate-dependent acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-ph phosphate to yield DXP.

Isoprenoid biosynthesis in bacteria: a novel pathway for the early steps leading to isopentenyl diphosphate.
TLDR
Results confirmed the earlier results obtained by incorporation of 13C-labelled acetate into the hopanoids of other bacteria and led to the identification of a novel biosynthetic route for the early steps of isoprenoid biosynthesis. Expand
Determination of the fluxes in the central metabolism of Corynebacterium glutamicum by nuclear magnetic resonance spectroscopy combined with metabolite balancing
TLDR
In vivo one component within these anaplerotic reactions is a back flux from the carbon 4 units of the tricarboxylic acid cycle to the carbon 3 units of glycolysis of 30.6% and the total net flux of the anaplerosis reactions was quantitated as 38.0%. Expand
Purification and properties of formaldehyde dehydrogenase and formate dehydrogenase from Candida boidinii.
TLDR
Evidence is presented which demonstrates that the reaction product of the formaldehyde-dehydrogenase-catalyzed oxidation of formaldehyde is S-formylglutathione rather than formate. Expand
Quantitative Determination of Metabolic Fluxes during Coutilization of Two Carbon Sources: Comparative Analyses withCorynebacterium glutamicum during Growth on Acetate and/or Glucose
TLDR
A glyoxylate cycle-deficient mutant of C. glutamicum, constructed by targeted deletion of the isocitrate lyase and malate synthase genes, exhibited impaired growth on acetate-glucose mixtures, confirming the predictions deduced from the metabolic flux analyses. Expand
A new type of transporter with a new type of cellular function: l‐lysine export from Corynebacterium glutamicum
TLDR
These results distinguish LysE as an exporter, which structurally represents a new type of translocator; demonstrates that exporters are also present for primary metabolites such as amino acids; and serves in one physiological function to link import with export activity. Expand
Kinetic properties of the glucose-6-phosphate and 6-phosphogluconate dehydrogenases from Corynebacterium glutamicum and their application for predicting pentose phosphate pathway flux in vivo.
TLDR
It is concluded that the oxidative pentose phosphate pathway in C. glutamicum is mainly regulated by the ratio of NADPH and NADP+ concentrations and the specific enzyme activities of both dehydrogenases. Expand
Linking Central Metabolism with Increased Pathway Flux: l-Valine Accumulation by Corynebacterium glutamicum
ABSTRACT Mutants of Corynebacterium glutamicum were made and enzymatically characterized to clone ilvD and ilvE, which encode dihydroxy acid dehydratase and transaminase B, respectively. These genesExpand
