BRITE hierarchy
Sysname
alpha-maltose-6'-phosphate 6-phosphoglucohydrolase
Reaction(IUBMB)
alpha-maltose 6'-phosphate + H2O = D-glucose + D-glucose 6-phosphate [RN:R00838 R06115]
Reaction(KEGG)
R00838 R06115(G);
(other) R00837 R06113(G)
Show
Substrate
alpha-maltose 6'-phosphate;
H2O [CPD:C00001]
Product
D-glucose [CPD:C00031];
D-glucose 6-phosphate [CPD:C00092]
Comment
Hydrolyses a variety of 6-phospho-alpha-D-glucosides, including alpha-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.
