Scheme diagram of the glycoptimus pathway. Key steps arabinose-5-phosphate isomerase (KDSD) and Ara5P aldolase (FSA) are shown as red arrows. In green is shown the oxidation of glycoladehyde to glycolate by glycoladehyde dehydrogenase encoding by aldA. Other abbreviations are XylA: xylose isomerase; AraA: arabinose isomerase; XylB: xylulo 5-P kinase, AraB: arabinose-5-P kinase; RpE: ribulose 5-P-3 epimerase; RpI: Ribose isomerase; TkT: transketolase; TaL: transaldolase; TpI: triose isomerase; FbA: fructose-1,6P2 aldolase; FbP; fructose-1,6P2 phosphatase, KdsD: arabinose-5-P isomerase; FsA, fructose-6-PP aldolase; AldA: glycolaldehyde reductase
