Xylitol enhances synthesis of propionate in the colon via cross-feeding of gut microbiota
Microbiome, 2021 Background Xylitol, a white or transparent polyol or sugar alcohol, is digestible by colonic microorganisms and promotes the proliferation of beneficial bacteria and the production of short-chain fatty acids (SCFAs), but the mechanism underlying these ...

Structure-Guided Engineering of Xylitol Dehydrogenase Cosubstrate Specificity [PDF]
Structure, 2006 Xylitol dehydrogenase (XDH) is one of several enzymes responsible for assimilating xylose into eukaryotic metabolism and is useful for fermentation of xylose contained in agricultural byproducts to produce ethanol. For efficient xylose utilization at high flux rates, cosubstrates should be recycled between the NAD+-specific XDH and the NADPH-preferring
