Function
Catalyzes the ATP-dependent phosphorylation of a wide variety of beta-D-glucosides, to produce 6-phospho-beta-D-glucosides including cellobiose-6'-P, gentiobiose-6'-P, cellobiitol-6-P, salicin-6-P, and arbutin-6-P. Is not able to phosphorylate alpha-D-glucosides. May have a dual role of kinase and transcriptional regulator of the cellobiose-PTS operon.
