WebNov 1, 2015 · Glycine betaine (GB) is an important osmoprotectant and synthesized by two-step oxidation of choline. Choline monooxygenase (CMO) catalyzes the first step of the pathway and is believed to be a rate limiting step for GB synthesis. Recent studies have shown the importance of choline-precursor supply for GB synthesis. WebMay 24, 2024 · Microbes convert choline, betaine, and carnitine to trimethylamine (TMA), which is then oxidized to TMAO by the insulin-regulated enzyme flavin-containing monooxygenase 3 in the host liver. TMAO is closely associated with the occurrence of cardiovascular and several related diseases.
WebLytic polysaccharide monooxygenase (LPMO) is a newly defined oxidase in lignocellulosic degradation systems that significantly fuels hydrolysis. LPMO accepts electrons from … WebThe first oxidation is catalyzed by choline monooxygenase (CMO) and the second oxidation is catalyzed by NAD+-dependent betaine aldehyde dehydrogenase. Moreover, in plants, the cytosolic enzyme, named N -methyltransferase, catalyzes the conversion of phosphoethanolamine to phosphocholine.
WebLytic polysaccharide monooxygenase (LPMO) is a newly defined oxidase in lignocellulosic degradation systems that significantly fuels hydrolysis. LPMO accepts electrons from wide sources, such as cellobiose dehydrogenase (CDH), glucose-methanol-choline (GMC) oxidoreductases, and small phenols.
