- ID: EG10165
- Name: glucose-specific phosphotransferase enzyme IIA component, crr
- Organism: E. coli
- UniProt ID: P69783
- Description: EG10165 codes for the glucose-specific phosphotransferase enzyme IIA component which is part of the sugar transporting phosphotransferase system (PTS) . PTS transports sugars such as glucose, mannose, etc. into prokaryotic cells and then phosphorylates them . In this case, the glucose-specific phosphotransferase enzyme IIA component, is the enzyme that catalyzes the reaction transporting glucose into the cell. It catalyzes the following reaction: [Protein]-N(pi)-phospho-L-histidine + D-glucose(Side 1) <=> [protein]-L-histidine + D-glucose 6-phosphate .

- Expression Level: high
- Expression Level Hypothesis: The crr gene is part of the the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). It is needed by the cell since it is the enzyme that catalyzes the reaction transporting glucose into the cell. Glucose is a vital component for the cell..
- Expression Level References and Description: The ptsP gene was not available in the Mycoplasma genitalium file, but it was found in the E. coli proteome.
- Expression Time: At which time should the gene be expressed in the lifecycle of our organism? Early
- Expression Level Hypothesis: Glucose is needed for cell respiration, which is essential for cellular growth. Thus, the gene needs to be expressed early.
- Expression Time References and Description: Research description above and UniProt.
- Other Components: glpK glpK, glycerol kinase
- Possible Dependencies: Histidine kinase A histidine kinase is needed since it is the enzyme that catalyzes the reaction that adds a phosphate group to the protein L-histidine . This in turn, creates [Protein]-N(pi)-phospho-L-histidine which is needed for this reaction..
- Process: phosphoenolpyruvate-dependent sugar phosphotransferase system
- Inputs: [Protein]-N(pi)-phospho-L-histidine, D-glucose(Side 1)
- Outputs: [protein]-L-histidine, D-glucose 6-phosphate(Side 2)
