Protein

Endoglucanase 2

Gene

GLU5

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Hydrolyzes 1,4-beta-glycosyl linkages of 1,4-beta-glucans and 1,3-1,4-beta-glucans. Possesses broad substrate specificity for hemicelluloses of type II cell walls. Substrate preference is carboxymethyl-cellulose > 1,3-1,4-beta-glucan > lichenan > arabinoxylan > phospho-swollen cellulose > xylan > glucomannan. May participate in lateral root development.2 Publications

Catalytic activityi

Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.

pH dependencei

Optimum pH is 5.3-5.6 with 1,3-1,4-beta-glucan as substrate (at 35 degrees Celsius).1 Publication
