Expected Taxonomic Range:
Ethylene glycol has many applications commercially. It is used in antifreeze solutions and for the chemical synthesis of glyoxal, glycolate and glyoxylate. Glyoxylate is a building block for a variety of molecules of industrial interest. While Escherichia coli encodes the enzymes shown in this pathway by which it can degrade ethylene glycol to glyoxylate and subsequently 3-phosphoglycerate which can enter central metabolism through glycolysis, wild type cannot metabolize this alcohol at a sufficient rate to support growth. However, certain mutant strains with altered patterns of gene expression, can grow on ethylene glycol as a total source of carbon and energy. Some strains of Pseudomonas putida may also express all or part of this pathway and are hence able to metabolize ethylene glycol to glyoxylate or further [Muckschel12].
