although the beta-glucoside kinase was previously shown to catalyze the phosphorylation of many beta-glucosides that serve as growth substrates ( i.e. , gentiobiose , cellobiose , cellobiitol , salicin , arbutin , methyl beta-d-glucoside , and phenyl beta-d-glucoside ) , mutant analysis and induction studies indicate that it functions only in the metabolism of gentiobiose , cellobiose , and cellobiitol .
