General annotation (Comments)

Function	Phospho-alpha-glucosidase that catalyzes the hydrolysis of p-nitrophenyl-alpha-D-glucopyranoside 6-phosphate, but is not able to cleave 'natural' phospho-alpha-glucosides produced via the phosphoenolpyruvate-dependent sugar phosphotransferase system (PEP-PTS).
Cofactor	Binds 1 NAD per subunit. Binds 1 manganese ion per subunit.
Subunit structure	Homotetramer.
Induction	By maltose and methyl-alpha-D-glucoside.
Sequence similarities	Belongs to the glycosyl hydrolase 4 family.
biophysicochemical properties	Kinetic parameters: KM=58.3 µM for p-nitrophenyl-alpha-D-glucopyranoside 6-phosphate Ref.2 Vmax=4.4 µmol/min/mg enzyme with p-nitrophenyl 6-phospho-alpha-D-glucoside as substrate
