Fig. 1

Canonical fungal and bacterial l-arabinose and d-xylose metabolism are additionally overlaid. Included are most known or putative routes for d-arabitol and xylitol interconversion. Cofactor annotations were left generally as NAD(P)H instead of species-specific. Please refer to Fig. 14 for gene-protein-reaction rules inferred from this study.
