General Information | Comment | Organism |
---|---|---|
malfunction | the glpD mutant strain GPM52 (glpD gene disrupted between nucleotides 555 and 556, resulting in a truncated protein of 185 amino acids) does not grow at all in glycerol-containing medium | Mycoplasma pneumoniae |
metabolism | glycerol is one of the few carbon sources that can be utilized by Mycoplasma pneumoniae. Glycerol metabolism involves uptake by facilitated diffusion, phosphorylation, and the oxidation of glycerol 3-phosphate to dihydroxyacetone phosphate, a glycolytic intermediate. Glycerol metabolism is important for cytotoxicity of Mycoplasma pneumoniae with the enzyme being important but not essential, overview | Mycoplasma pneumoniae |
physiological function | the formation of hydrogen peroxide by GlpD is crucial for cytotoxic effects of Mycoplasma pneumoniae. The glycerol 3-phosphate oxidase encoded by glpD is essential for glycerol utilization | Mycoplasma pneumoniae |
