IntEnz Enzyme Nomenclature
EC 3.2.1.122

Names

Accepted name:
maltose-6'-phosphate glucosidase
Other name:
phospho-α-glucosidase
Systematic name:
maltose-6'-phosphate 6-phosphoglucohydrolase

Reaction

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.
