The Mechanism of Regulation of Chemolithotrophic Sulfur Oxidation in Pseudaminobacter salicylatoxidans KCT001
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 Although the mode of repression of the sulfur oxidation (sox) operon has been elucidated in recent times the mechanism of its derepression is not yet known. Here we propose a comprehensive mechanism of sox gene expression by envisaging redox modulation of soxR as the key to the repression as well as derepression of sox-mediated thiosulfate oxidation Pseudaminobacter salicylatoxidans KCT001. While soxR, rendered to its …

Engineering Fatty Acid Oxidation Pathway for the Production of Yeast-based Monomers
Abstract: Yeast-based monomers have a wider application in many fields and used for polymer production. Yeast system is used to improve the production of such valuable monomers by exploiting the metabolic pathways of interest. Alkane-utilizing yeasts mediate the fatty acid catabolism inside the peroxisomes primarily through beta (β) oxidation pathway, which breaks up the long chain fatty acids resulting in the synthesis of energy producing molecules. This allows the reduced inflow …
