eliminated in the urine.Erythritolalso lacks the laxative properties of other polyols likesorbitoland xylitol. By dephosphorylating D-erythrose-4-phosphate to D-erythrose and subsequently reducing it to erythritol in yeast, thepentose phosphate(PPP) pathway produces erythritol (Antoniêtoet al., 2022)...
higher activity of PPP and supports the co-utilization phenotype of SCD00 for xylose and glucose. There is more than 3 log2fold overexpression of proteins involved in the transport and metabolism of ribose sugar, such as – D-ribose periplasmic binding protein ([Locus_tag = ECB_02650), ...

All of the genes for xylose assimilation, the oxidative pentose phosphate pathway (PPP), glycolysis, the tricarboxylic acid cycle (TCA) and ethanol production were present in isoforms similar to those found in other yeasts (Fig. 5). Transcripts of GND1 are strongly induced by growth on xylose...
Beyond the first steps of xylose metabolism, the overexpression of genes related to the non-oxidative phase of the pentose phosphate pathway (PPP) has also been shown to positively influence the growth rate on xylulose [29]. Although these factors seem to be important for xylose metabolism, ...
In both pathways xylulose is generated, phosphorylated by xylulose kinase, and metabolized in the Pentose Phosphate Pathway (PPP) (Fig. 2A). Sign in to download hi-res image Fig. 2. Lignocellulosic sugar utilization pathways. (A) Pentose utilization pathways. XI, xylose isomerase; XR, xylose ...

Our results raise the possibility that the xylose-specific effect is caused by the inhibition of the xylose metabolic pathway such as the non-oxidative PPP or xylose uptake through transporter. In fact, this possibility was supported by the accumulation of metabolic intermediates involved in the non...
integrated data from enzyme activity analyses and quantitative metabolite profiling into an ad hoc reduced model that included XR/XDH pathway, pentose phosphate pathway (PPP), and two lumped reactions describing glycolysis, and used this model for MCA [28]. In this work, we used the Optimization...
