Structural and functional analysis of pyruvate kinase from Corynebacterium glutamicum.
Pyruvate kinase activity is an important element in the flux control of the intermediate metabolism. The purified enzyme from Corynebacterium glutamicum demonstrated a marked sigmoidal dependence of the initial rate on the phosphoenolpyruvate concentration. In the presence of the negative allosteric effector ATP, the phosphoenolpyruvate concentration at the half-maximum rate (S0.5) increased fr...
متن کاملStructural basis for cytokinin production by LOG from Corynebacterium glutamicum
"Lonely guy" (LOG) has been identified as a cytokinin-producing enzyme in plants and plant-interacting fungi. The gene product of Cg2612 from the soil-dwelling bacterium Corynebacterium glutamicum was annotated as an LDC. However, the facts that C. glutamicum lacks an LDC and Cg2612 has high amino acid similarity with LOG proteins suggest that Cg2612 is possibly an LOG protein. To investigate t...
متن کاملAnalysis of the Corynebacterium glutamicum dapA promoter.
Deletion and mutational analysis of the promoter P-dapA from Corynebacterium glutamicum was performed to identify regions and particular nucleotides important for its function. An extended -10 region and a stretch of six T's at positions -55 to -50 were found to be the most important elements in the promoter function. The results of mutational analysis of P-dapA are consistent with the conclusi...
متن کاملExopolyphosphatases PPX1 and PPX2 from Corynebacterium glutamicum.
Corynebacterium glutamicum accumulates up to 300 mM of inorganic polyphosphate (PolyP) in the cytosol or in granules. The gene products of cg0488 (ppx1) and cg1115 (ppx2) were shown to be active as exopolyphosphatases (PPX), as overexpression of either gene resulted in higher exopolyphosphatase activities in crude extracts and deletion of either gene with lower activities than those of the wild...
متن کاملAnalysis and engineering of metabolic pathway fluxes in Corynebacterium glutamicum.
The Gram-positive soil bacterium Corynebacterium glutamicum was discovered as a natural overproducer of glutamate about 50 years ago. Linked to the steadily increasing economical importance of this microorganism for production of glutamate and other amino acids, the quest for efficient production strains has been an intense area of research during the past few decades. Efficient production stra...
