The glyoxylate bypass of Ralstonia eutropha.
The glyoxylate bypass genes aceA1 (isocitrate lyase 1, ICL1), aceA2 (isocitrate lyase 2, ICL2) and aceB1 (malate synthase, MS1) of Ralstonia eutropha HF39 were cloned, sequenced and functionally expressed in Escherichia coli. Interposon-mutants of all three genes (DeltaaceA1, DeltaaceA2 and DeltaaceB1) were constructed, and the phenotypes of the respective mutants were investigated. Whereas R. ...
متن کاملIdentification and characterization of glxR, a gene involved in regulation of glyoxylate bypass in Corynebacterium glutamicum.
A corynebacterial clone, previously isolated by scoring repression of lacZYA fused to the aceB promoter of Corynebacterium glutamicum, was analyzed further. In the clone, an open reading frame designated glxR, consisting of 681 nucleotides and encoding a 24,957-Da protein, was found. The molecular mass of a native GlxR protein was estimated by gel filtration column chromatography to be 44,000 D...
متن کاملRegulation of glyoxylate metabolism in Escherichia coli K-12.
The relative contributions of the dicarboxylic acid and the tricarboxylic acid cycles to the oxidative catabolism of glyoxylate in Escherichia coli K-12 were deduced by analysis of mutant strains that were blocked in the formation of glyoxylate carboligase and of malate synthase G (the "glycolate form" of malate synthase). Mutant strains unable to form malate synthase G were unimpaired in their...
متن کاملBypass rewiring and robustness of complex networks.
A concept of bypass rewiring is introduced, and random bypass rewiring is analytically and numerically investigated with simulations. Our results show that bypass rewiring makes networks robust against removal of nodes including random failures and attacks. In particular, random bypass rewiring connects all nodes except the removed nodes on an even degree infinite network and makes the percolat...
متن کاملOverexpression of isocitrate lyase-glyoxylate bypass influence on metabolism in Aspergillus niger.
In order to improve the production of succinate and malate by the filamentous fungus Aspergillus niger the activity of the glyoxylate bypass pathway was increased by over-expression of the isocitrate lyase (icl) gene. The hypothesis was that when isocitrate lyase was up-regulated the flux towards glyoxylate would increase, leading to excess formation of malate and succinate compared to the wild...
