Oligo- 1 - 6 -D-glucosidases

Oligo-1,6-D-glucosidase-sucrose a-D-glucohydrolase ( isomaltase-sucrase ) is an intestinal membrane enzyme consisting of two active moieties each with its hydrolytic site available for nutrient digestion at the luminal-cell interface (see p. 451).  

01igo-l,6-D-glucosidase together with a-D-glucosidase has been shown to be produced by Bacillus brevis in the presence of maltose, maltotriose, etc. (see p. 457).  

A 4-nitrophenyl a-D-glucopyranoside-hydrolysing a-D-glucosidase of a thermophile, Bacillus thermoglucosidius, has been purified to an electrophoreti-cally homogeneous state (see p. 458).  

45 Oligo-(1 - 6)-D-glucosidases Various aspects of the enzymology of oligo-(l dextrinase ) from peas have been reported.

Studies on the specificities of purified a-D-glycosyl hydrolases of about eight kinds of yeast are summarized in Table XI. The enzymes of Saccharomyces cerevisiae, namely, a-D-glucosidase and oligo-(1 — 6)-D-glucosidase (EC 3.2.1.10), have been examined the most thoroughly. 

Electrophoresis on polyacrylamide gels of materials from brush-border membranes of siblings with a deficiency of sucrose a-D-glucohydrolase-oligo-1,6-D-glucosidase ( sucrase - isomaltase ) did not reveal the normal protein band associated with the complex. ...
