Protein

Glucose-1-phosphatase

Gene

agp

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Absolutely required for the growth of E.coli in a high-phosphate medium containing G-1-P as the sole carbon source.

Catalytic activityi

Alpha-D-glucose 1-phosphate + H2O = D-glucose + phosphate.

Enzyme regulationi

Independent from inorganic phosphate availability, and apparently submitted to catabolite repression, it is positively controlled by cAMP and the cAMP receptor protein.

pH dependencei

Optimum pH is about 4.
