Pathway-level acceleration of glycogen catabolism by a response regulator in the cyanobacterium Synechocystis species PCC 6803.
Response regulators of two-component systems play pivotal roles in the transcriptional regulation of responses to environmental signals in bacteria. Rre37, an OmpR-type response regulator, is induced by nitrogen depletion in the unicellular cyanobacterium Synechocystis species PCC 6803. Microarray and quantitative real-time polymerase chain reaction analyses revealed that genes related to sugar...
متن کاملPathway of butyrate catabolism by Desulfobacterium cetonicum.
Desulfobacterium cetonicum 480 oxidized butyrate to 1 mol of acetate and 2 mol of CO2; this reaction was coupled to reduction of sulfate to sulfide. Butyrate was activated by coenzyme A (CoA) transfer from acetyl-CoA, and butyryl-CoA was oxidized to acetyl-CoA by a classical beta-oxidation pathway. Acetyl-CoA was oxidized through the acetyl-CoA/carbon monoxide dehydrogenase pathway. There was a...
متن کاملAn Oxidative Pathway of Deoxyribose Catabolism
High-throughput genetics is a powerful approach to identify new genes involved in bacterial carbon catabolism. Here, we used genome-wide fitness assays to identify a novel pathway for 2-deoxy-D-ribose catabolism in Pseudomonas simiae WCS417. The genes that were important for deoxyribose utilization ...
متن کاملA novel metabolic pathway for glucose production mediated by α-glucosidase-catalyzed conversion of 1,5-anhydrofructose.
α-Glucosidase is in the glycoside hydrolase family 13 (13AG) and 31 (31AG). Only 31AGs can hydrate the D-glucal double bond to form α-2-deoxyglucose. Because 1,5-anhydrofructose (AF), having a 2-OH group, mimics the oxocarbenium ion transition state, AF may be a substrate for α-glucosidases. α-Glucosidase-catalyzed hydration produced α-glucose from AF, which plateaued with time. Combined reacti...
متن کاملElucidation of the complete Azorhizobium nicotinate catabolism pathway.
A complete pathway for Azorhizobium caulinodans nicotinate catabolism has been determined from mutant phenotype analyses, isolation of metabolic intermediates, and structural studies. Nicotinate serves as a respiratory electron donor to O2 via a membrane-bound hydroxylase and a specific c-type cytochrome oxidase. The resulting oxidized product, 6-hydroxynicotinate, is next reduced to 1,4,5,6-te...
