Xylulose 1-Phosphate, Ribulose-1-Phosphate and serine pathway connected to central carbon metabolism for conversion of pentose and hexose into GA and EG. XI: xylose isomerase; DTE: d-tagatose 3-epimerase; FUCK: fuculokinase: FUCA: fuculo-phosphate aldolase; KHKC: ketohexokinase C; Aldo-B: mammalian aldolase B; ScFBA: S. cerevisiae FBP aldolase; RHAK: L-rhamno-1-P kinase; RHAD: Rhamno-1-P aldolase; ICL: isocitrate lyase; AlDH: aldehyde dehydrogenase: ALR: aldehyde reductase. Inset of Fig. 4 is shown the two serine pathways. TPI: triose phosphate Isomerase; GpdH: glyceraldehyde-3-phosphate dehydrogenase; SerA: 3-hydroxypyruvate dehydrogenase; SerC: serine: α-KG transaminase; SerB: phosphoserine phosphatase; AGT: alanine-glyoxylate transaminase; KDC: α-keto-acid decarboxylase; SDC: serine αdecarboxylase; AAo: amino acid oxidase. Additional details on enzyme and encoding genes are given in Additional file 1: Table S3
