transferasa-glucosidasa
Scope note: 1,4-alfa-D-glucan-1,4-alfa-D-glucan 4-alfa-D-glucosiltransferasa--dextrina 6 alfa-D-glucanohidrolasa. Sistema enzimático con actividad 4-alfa-glucanotransferasa (EC 2.4.1.25) y amilo-1,6-glucosidasa (EC 3.2.1.33). Como transferasa, transfiere un segmento de un 1,4-alfa-D-glucano hacia una nueva posición 4 en un aceptor, que puede ser glucosa u otro 1,4-alfa-D-glucano. Como glucosidasa, cataliza la endohidrólisis de enlaces 1,6-alfa-D-glucosídicos en puntos de ramificación de las cadenas de residuos de alfa-D-glucosa enlazados en 1,4. En la enfermedad por almacenamiento de glucógeno tipo III se observa una deficiencia de la actividad de la amilo-1,6-glucosidasa.

Scope note: 1,4-alpha-D-Glucan-1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase/dextrin 6 alpha-D-glucanohydrolase. An enzyme system having both 4-alpha-glucanotransferase (EC 2.4.1.25) and amylo-1,6-glucosidase (EC 3.2.1.33) activities. As a transferase it transfers a segment of a 1,4-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or another 1,4-alpha-D-glucan. As a glucosidase it catalyzes the endohydrolysis of 1,6-alpha-D-glucoside linkages at points of branching in chains of 1,4-linked alpha-D-glucose residues. Amylo-1,6-glucosidase activity is deficient in glycogen storage disease type III.
