Overflow metabolism
WebDec 14, 2024 · Acetate overflow appears to be a frequently encountered event in the protein-overproducing E. coli which is incapable of properly coordinating glucose metabolism. This phenomenon is generally ascribed to the lower activity of the TCA cycle and respiratory chain relative to the uptake rate of glucose [ 25 ]. WebJan 11, 2024 · The overflow function of these enzymes is also supported by the observation that acetogens lacking the AOR enzyme, such as A. woodii, are prone to inhibition by CO …

WebOverflow metabolism is a common phenomenon observed at higher glycolytic flux in many bacteria, yeast (known as Crabtree effect), and mammalian cells including cancer cells … Overflow metabolism refers to the seemingly wasteful strategy in which cells incompletely oxidize their growth substrate (e.g. glucose) instead of using the respiratory pathway, even in the presence of oxygen. As a result of employing this metabolic strategy, cells excrete (or "overflow") metabolites like lactate, acetate and ethanol. Incomplete oxidation of growth substrates yields less energy (e.g. ATP) than complete oxidation through respiration, and yet overflow metabolism—kno…
WebDec 1, 2010 · The phenomenon of overflow metabolism has been studied widely over the years and it is commonly believed to be caused by an imbalance between the fluxes of glucose uptake and those for energy production and biosynthesis [7, 8].Several explanations such as the saturation of catalytic activities in the tricarboxylic acid (TCA) cycle [9, 10] …
