TL;DR: 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.

TL;DR: 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.

TL;DR: 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.

TL;DR: Incorporation of 13C-labeled glycerol or pyruvate into the ubiquinone Q8 of Escherichia coli mutants lacking enzymes of the triose phosphate metabolism and of (U-13C6)glucose into the triterpenoids of the hopane series of Zymomonas mobilis showed that glyceraldehyde 3-phosphate and a C2 unit derived from pyruVate decarboxylation were the

TL;DR: Evidence is presented which demonstrates that the reaction product of the formaldehyde-dehydrogenase-catalyzed oxidation of formaldehyde is S-formylglutathione rather than formate.
