Amylo-l,6-D-glucosidases

The role of amylo-l,6-D-glucosidase in the metabolism of exogenous and endogenous carbohydrates in Aerobacter aerogenes, E. coli, and Streptococcus mutans has been discussed.

In the method of Cori and Lamer, glycogen (or amylopectin) is completely digested by the concurrent action of muscle phosphorylase and amylo-(l 6)-glucosidase. n-Glucose (which arises only from residues attached to C6 of an adjacent residue) and n-glucosyl phosphate (which is obtained from all other residues) are determined, and the branch-point content is calculated from the proportion of D-glucose. Only 10-15 mg. of glycogen is required for each assay the method has been applied to more...

The properties of new starch-degrading enzymes have been reviewed, Studies on glycogen-storage diseases, concerned mainly with a-D-glucosidases, have also included discussions on amylo-l,4-glucosidase and amylo-l,6-glucosidase activities. ... 

Amylo-(1 6)-glucosidase is the a-D-(l— 6)-debranching enzyme found in animal skeletal muscle, where it debranches glycogen. Methods of preparation have been described, but there is no knowledge regarding its structure or physical properties.
