As a new member of the glucose-phosphorylating enzymes, the ATP-dependent hexokinase from the hyperthermophilic crenarchaeon Sulfolobus tokodaii was purified, identified, and characterized. Our results revealed that the enzyme differs from other known enzymes in primary structure and its broad substrate specificity for both phosphoryl donors and acceptors.
