Protein

Sugar phosphatase YidA

Gene

yidA

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

Functioni

Catalyzes the dephosphorylation of different sugar phosphates including erythrose-4-phosphate (Ery4P), ribose-5-phosphate (Ribu5P), fructose-1-phosphate (Fru1P), fructose-6-phosphate (Fru6P), glucose-6-P (Glu6P), and also imidodiphosphate (Imido-di-P) and acetyl phosphate (Acetyl-P). Selectively hydrolyzes alpha-D-glucose-1-phosphate (Glu1P) and has no activity with the beta form.2 Publications

Catalytic activityi

Sugar phosphate + H2O = sugar + phosphate.1 Publication

Cofactori

Mg2+1 Publication, Mn2+1 Publication, Co2+1 Publication, Zn2+1 PublicationNote: Magnesium. Can also use other divalent metal cations as manganese, cobalt or zinc.1 Publication
