Variations in sugar utilisation pathways in O. oeni. A. The predicted pathway for the assimilation of L-arabinose and L-xylulose in O. oeni. EC numbers are provided for each enzymatic step. O. oeni strains displaying metabolic blocks at individual enzymatic steps are also indicated. Arrows are color-coded according to the location of the ORF in parts B and C. B. A strain-specific genomic insertion predicted to impart the ability to utilise L-xylulose. Individual ORFs surrounding this locus are shown for each strain. Orthologous ORFs are positioned vertically and are color coded according to their conservation status (conserved, pink; strain-specific, light-blue). ORFs predicted to be directly involved in the utilisation of L-xylulose are color-coded according to their metabolic role (green, L-xylulose utilisation, orange, L-xylulose and L-arabinose utlisation). C. A strain-specific genomic insertion predicted to impart the ability to utilise arabinan and L-arabinose. Shading is identical to part B except for the presence of ORFs involved directly in the utilisation of arabinan and L-arabinose (shaded yellow).
