Lysine uptake and exchange in Corynebacterium glutamicum.
Resting cells of Corynebacterium glutamicum (ATCC 13032) accumulate [14C]lysine by a transport system with a relatively high affinity (10 microMs) and a low maximum velocity (0.15 nmol/min per mg [dry weight]). Uptake of lysine was not inhibited by uncouplers or by ionophores affecting the ion gradients and the energetic state of the cell. Analysis of intracellular amino acid concentrations dur...
متن کاملIsoprenoid Pyrophosphate-Dependent Transcriptional Regulation of Carotenogenesis in Corynebacterium glutamicum
Corynebacterium glutamicum is a natural producer of the C50 carotenoid decaprenoxanthin. The crtEcg0722crtBIYEb operon comprises most of its genes for terpenoid biosynthesis. The MarR-type regulator encoded upstream and in divergent orientation of the carotenoid biosynthesis operon has not yet been characterized. This regulator, named CrtR in this study, is encoded in many actinobacterial genom...
متن کاملEfficient aerobic succinate production from glucose in minimal medium with Corynebacterium glutamicum
Corynebacterium glutamicum, an established industrial amino acid producer, has been genetically modified for efficient succinate production from the renewable carbon source glucose under fully aerobic conditions in minimal medium. The initial deletion of the succinate dehydrogenase genes (sdhCAB) led to an accumulation of 4.7 g l(-1) (40 mM) succinate as well as high amounts of acetate (125 mM)...
متن کاملEngineering of Acetate Recycling and Citrate Synthase to Improve Aerobic Succinate Production in Corynebacterium glutamicum
Corynebacterium glutamicum lacking the succinate dehydrogenase complex can produce succinate aerobically with acetate representing the major byproduct. Efforts to increase succinate production involved deletion of acetate formation pathways and overexpression of anaplerotic pathways, but acetate formation could not be completely eliminated. To address this issue, we constructed a pathway for re...
متن کاملGlycerol as a substrate for aerobic succinate production in minimal medium with Corynebacterium glutamicum
Corynebacterium glutamicum, an established microbial cell factory for the biotechnological production of amino acids, was recently genetically engineered for aerobic succinate production from glucose in minimal medium. In this work, the corresponding strains were transformed with plasmid pVWEx1-glpFKD coding for glycerol utilization genes from Escherichia coli. This plasmid had previously been ...
