Under these limiting conditions, we find that glutathione catabolism by CHAC1 supports the mitochondrial cysteine pool to sustain the function of the Fe-S proteins critical to oxidative metabolism. We find that disrupting Fe-S cluster synthesis under cysteine restriction protects against the induction ...

DsrC finally transfers the sulfur to the dissimilatory sulfite reductase (DsrAB) acting in the oxidative direction, i.e. in reverse of the reaction catalyzed in sulfate reducers (see last figure). The oxidation of sulfite, the product of the DsrAB catalyzed reaction in sulfur oxidizers, to ...
Particularly, the temporary elevation of MaNIP1 expression lessened the chlorophyll degradation prompted by MaNYC1 in banana fruits, suggesting that MaNIP1 negatively impacts chlorophyll catabolism through its effect on MaNYC1 breakdown. The combined data support the existence of a post-translational ...

Curiously, carotenoid cleavage dioxygenase (CmCCD1), which produces volatile apoca- rotenoids from β-carotene through a 9,10-oxidative cleav- age, is upregulated both in orange-fleshed varieties as well as in white varieties that accumulate neither carotenoids nor apocarotenoids...
GOGAT catalyzes the reductive transfer of the amide group of glutamine to the keto position of 2-oxoglutarate to yield two molecules of glutamate. The GS/GOGAT pathway ultimately requires ATP and reducing power, which are generated by photosynthesis and oxidative catabolism of carbohydrates, and ...
PDR-1 regulation affects HG degradation and pectin-related catabolism The observed growth phenotypes cannot answer the question of whether PDR-1 regulates intracellular or extracellular processes, or both, and to what extent PDR-1 is involved in the regulation. To address this question, a composition...

The shunting of metabolites from the TCA cycle into other pathways (cataplerosis) is part of the fundamental biochemistry of cell growth, and it emphasizes the versatility of the TCA cycle: rather than serving a purely oxidative function as a source of reducing equivalents for the electron ...
