Beta-glucoside kinase () is an enzyme that catalyzes the chemical reaction
The enzyme first characterised from Aerobacter aerogenes converts cellobiose to its monophosphate, 6-phospho-β-D-glucosyl-(1,4)-D-glucose by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).
This enzyme is a transferase, specifically one transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:cellobiose 6-phosphotransferase. This enzyme is also called beta-D-glucoside kinase (phosphorylating).
