Protein
Sugar phosphatase YbiV
Gene
ybiV, supH, b0822, JW0806
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolysis of sugar phosphate to sugar and inorganic phosphate. Has a wide substrate specificity catalyzing the hydrolysis of ribose-5-phosphate, glucose-6-phosphate, fructose-1-phosphate, acetyl-phosphate, glycerol-1-phosphate, glycerol-2-phosphate, 2-deoxy-glucose-6-phosphate, mannose-6-phosphate and fructose-6-phosphate. Appears to have a low level of phosphotransferase activity using monophosphates as the phosphate donor.3 Publications

Catalytic activityi

Sugar phosphate + H2O = sugar + phosphate.1 Publication

Cofactori

Magnesium. Can also use other divalent metal cations as manganese, cobalt and zinc.1 Publication

Kineticsi

Glucose-6-phosphate is also a good substrate with a relative activity of 62.5% versus the activity with ribose-5-phosphate.

  2. KM=1.4 mM for fructose-1-phosphate (in the presence of magnesium ion as cofactor and at pH 9)
  3. KM=2.4 mM for ribose-5-phosphate (in the presence of magnesium ion as cofactor and at pH 9)
  4. KM=3.1 mM for glucose-6-phosphate (in the presence of magnesium ion as cofactor and at pH 9)
  5. KM=4.9 mM for acetyl-phosphate (in the presence of magnesium ion as cofactor and at pH 9)
  6. KM=6 mM for ribose-5-phosphate (at pH 5.4)
  7. KM=6 mM for glycerol-1-phosphate (at pH 5.4)
  8. KM=4.5 mM for glycerol-2-phosphate (at pH 5.4)
