| Comment |
Hydrolyses a variety of 6-phospho-D-glucosides, including maltose
6-phosphate, alpha,alpha-trehalose 6-phosphate, sucrose 6-phosphate
and p-nitrophenyl-alpha-D-glucopyranoside 6-phosphate (as a
chromogenic substrate). The enzyme is activated by FeII, MnII, CoII
and NiII. It is rapidly inactivated in air. |
