Some taxa known to possess this pathway include : Escherichia coli K-12 substr. MG1655
Glycerol dissimilation in Escherichia coli K-12 is usually initiated by the ATP-dependent glycerol kinase (encoded by glpK), which phosphorylates glycerol to sn-glycerol 3-phosphate. However, upon inactivation of the kinase, it may be replaced by the gldA NAD+-linked L-1,2-propanediol dehydrogenase / glycerol dehydrogenase [Tang82]. This enzyme is cryptic in the wild type, and is only activated by mutation. It exhibits broad substrate specificity (it has a lower Km value for (S)-propane-1,2-diol than for glycerol) and its true physiological role remains uncertain [Blattner93, Jin83].
Variants: glycerol and glycerophosphodiester degradation, glycerol degradation I, glycerol degradation II, glycerol degradation III, glycerophosphodiester degradation, superpathway of glycerol degradation to 1,3-propanediol
