EC 3.2.1.122     
Accepted name: maltose-6′-phosphate glucosidase
Reaction: α-maltose 6′-phosphate + H2O = D-glucose + D-glucose 6-phosphate
Other name(s): phospho-α-glucosidase; maltose-6′-phosphate 6-phosphoglucohydrolase
Systematic name: α-maltose-6′-phosphate 6-phosphoglucohydrolase
Comments: Hydrolyses a variety of 6-phospho-α-D-glucosides, including α-maltose 6′-phosphate, α,α-trehalose 6-phosphate, sucrose 6-phosphate and p-nitrophenyl-α-D-glucopyranoside 6-phosphate (as a chromogenic substrate). The enzyme is activated by FeII, MnII, CoII and NiII. It is rapidly inactivated in air.
